Snow Fleas: That Dirty Snow is Alive!
Think of the Earth as a giant cherry tomato with skewer running right through it. Scientists believe that while our solar system was in the process of forming something really big, another “protoplanet” hit the Earth and slapped it out of kilter. So, as most kids forget by the end of high school, the Earth spins on a skewer that is 23.5 degrees off its orbital axis. As the planet takes its yearly trek around the sun, the Northern hemisphere either receives direct light, as in summer or indirect light, as in winter -- which creates seasons that are “near perfectly calibrated to maintain life”, according to Universe Today. Thanks to that skewer, New Englanders enjoy (or loathe as the case may be) typically long, cold, and snowy winters.
As winter winds down in New England, ice and snow begin to loosen their grip on the landscape, and signs of spring begin to emerge, sometimes literally right out of the snow. By March steam pours from vents of sugar-houses as sugar-makers begin boiling maple sap down into Vermont’s signature liquid. On those same late winter days when the temps begin to push into the 50s and the streams begin to run full of snow-melt, a hiker or skier might come upon a patch of snow that looks at first like it was dusted with cinders or black sand. That black on white contrast arrests the eyes.
What at first looks like fine dirt turns out to be a little millimeter-long hexapod, the springtail, or as they're colloquially known, "snow fleas". Various springtails exist all over the planet, but they somehow manage to persist even in extreme winter climates like Antarctica and northern New England. These intrepid little snow enthusiasts turn up by the thousands per square meter, up to 10,000 of them in fact, according to legendary naturalist David Attenborough. Even at high elevations, in late winter springtails emerge from the snow in huge numbers on warm afternoons in order to feed on decomposing leaves or moss. Snow fleas represent not only the inevitable arrival of spring in the northern woods, but some of nature's amazing adaptations that allow for a specie's survival -- and perhaps has some benefits for humankind as well.

Snow fleas represent not only the inevitable arrival of spring in the northern woods, but some of nature's amazing adaptations that allow for a specie's survival -- and perhaps has some benefits for humankind as well.
First though, they’re not technically insects. Besides the number of body segments and the lack of compound eyes, an extra little appendage sets them apart from their taxonomic cousins: the spring tail which gives them their name. Called a “furcula” (same word root as “fork”), this adaptation seems particularly designed to allow the springtail to evade predators. The snow fleas’ exoskeleton is full of a “rubber-like protein called resilin, where a lot of the potential energy for the jump is stored,” according to an article in Wired magazine. Basically, springtails are always running around cocked and loaded. When threatened by a predator, like a spider or centipede, they deploy their ejection seat and launch 100s times their body-length -- the equivalent of a person jumping over the Eiffel Tower (Attenborough). Unfortunately for these spring-loaded little launchers, they cannot control where they land, so their jump is a sort of randomizer. Then again, when there’s a party of 1000s of snow fleas, it probably doesn’t matter where you end up -- they just hop to the other side of the fiesta.
Still, the springtail has to survive the winter to make it to these spring bacchanals, and to weather the long New England winter, even at high elevations where winter runs even colder and longer, the snow flea uses a built-in anti-freeze to make it through. Tiny peptide chains known as anti-freeze proteins (AFPs), they allow a variety of organisms, among them fish, fungi, and plants, to survive extremely cold climates. AFPs operate at the molecular level “by binding to the surfaces of ice crystals as they start to form, inhibiting further growth,” according to an article by Steve Ritter in Chemical & Engineering News. By preventing the formation of ice crystals, AFPs prevent organisms from freezing solid, thus ensuring survival.
Snow fleas have another chemical defense, this one specifically designed to deter predators: a chlorine compound called Sigillan A. Researchers in Germany have isolated something that “is unique in that it is a new class of natural products that features a chemical scaffold that could find application in insect control,” as reported in an article by Sarah Evarts in Chemical & Engineering News. Scientists were surprised to find any chlorine compounds at all produced by a land animal. “It’s not often that scientists find any halogens in natural products made by terrestrial organisms … here, there’s not just one chlorine, but five chlorines,” according to John Pickett, chemical ecologist from Rothamsted Research Station in England.
Snow fleas’ chemical adaptations, AFPs in particular, may come to help humans in a couple of ways, perhaps most importantly with organs for transplant. According to a piece in Phys.org, Drs. Laurie Graham and Peter Davis [of Queens University] “found that the potent protein produced by the fleas to protect themselves against freezing is capable of inhibiting ice growth by about six Celsius degrees.” This is significant because it would allow “organs to be stored at lower temperatures, expanding the time allowed between removal and transplant.” Moreover, snow fleas’ AFPs break down easily at higher temperatures. This is beneficial, explained Dr. Davies, Canada Research Chair in Protein Engineering, because AFPs used for organ transplant storage “will be cleared from a person’s system very quickly, reducing the possibility of harmful antibodies forming.” Thus, the potential for successful transplants increases dramatically.
Other studies show that springtail chemistry may also help bring about more effective freeze-resistant crops. But aside from their promising contributions to humanity, snow fleas are decomposers, and as such they perform an arguably more important role for humans: helping to maintain the balance and health of our northern forests by facilitating the breakdown of organic material. Decomposers maintain a healthy soil substrata on which trees and forests can thrive. And with those forests spread all over this skewed and changing planet, the humans who occupy it, for now, are still able to breathe.

Cotopaxi Beat Down
Field Trip: Cotopaxi, June 2013
Latest draft, April 2016
“No, no,” Pete said to Segundo in Spanish. “I’ve known this
man for eighteen years. He’s one
tough bastard. It’s not fitness;
it’s the altitude.”
I was on my knees, leaning on my ice-ax. Sleet, wind, and freezing rain pounded
down on us. I could make out the shadows of the two men in my headlamp. It must have been about 4 AM, with the
light just coming up on the glacier, but I hadn’t had the energy to
pull back the cuff of my glove to check my watch for the entire
three-plus hours we’d been slowly marching uphill.
“Solo faltamos trescientos metros,” Segundo said to Pete.
One tough bastard himself, our guide Segundo said we were only 300 meters from the summit. Another hour, he said. On the list of the many bad-asses I’ve
met in my life, Segundo is at the top of the list. He spoke in meters while I was on my knees, trying to convert meters to feet in my head. I’m not so quick with numbers, even in the best of circumstances. What I now know is that we were resting
there, near the top of a glacier, on the side of Ecuador’s second highest peak
and the world’s tallest active volcano, Cotopaxi, at about 18,300 feet. Since I don’t have any real
mountaineering ambitions, it is likely the highest I will ever go on foot.
I also now know that I was experiencing altitude sickness,
or Acute Mountain Sickness (AMS), and possibly even hypoxia. Whatever it’s called, my body was not
cooperating with my brain due to a lack of oxygen. While
from the outside the symptoms look like intoxication — and actually felt like
it — my brain was hyper-aware.
Though I was babbling incoherently, I remember perfectly the details
from the trek, the dialogue between Segundo and Pete in that moment — and,
ultimately, the decision to turn back.
Pete and I laughed later about the “eighteen years” line because it was
so random and specific at the same time — and short a couple years.
My most vivid memory on the glacier was setting tiny goals:
ten steps, just ten steps, then rest.
Then I’d count out five or six crunchy footfalls in the narrow beam of my
headlamp before I’d drop to my knees and rest on my ice-axe again. I have tested myself in many kinds of
endurance events, and this one blew them all away. I’d sooner run another marathon, barefoot and blindfolded,
than take another ten steps at 18,000 feet.
I might have even enjoyed the sensation, had it not been for
Thor’s Hammer knocking incessantly on the inside of my skull, a sensation I now
think was probably my pulse. This
was my biggest crime (and I should have known better): dehydration. I just could not get enough water into
my system. I should have had Advil
and coca leaves — the latter of which is renowned among indigenous people of
the Andes and climbers alike for its ability to counteract the symptoms of
AMS. By the time we reached the
high camp where I’d attempt to sleep, my head was pounding a thousand times
worse than the worst hangover I’d ever experienced.
So Pete and Segundo made the call to retreat, and I am
forever thankful for that decision.
I remember well the feeling of disappointment being eclipsed by a
massive sense of relief. The
weather was nasty, as it can often be at 18,000 feet. Later, when we stepped off the glacier, we were coated in a
layer of ice so that, when I bent my arm, all these little pieces of ice would
shatter off. There was little to
no chance we’d have a clear view from Cotopaxi’s famous cone summit, which I’m
sure made the decision to turn back a little easier.
Cotopaxi is the iconic symbol of the glaciated Andean
volcano: it rises to 19,347 feet above sea level, a mind-bogglingly massive
and, at a distance, perfectly symmetrical cone. And distances can be deceiving. Often referred to by indigenous locals as the “Shy Lady”
because it’s so often shrouded in clouds, Cotopaxi literally means “shining
pile” in Kichwa, which is still widely spoken in the Andes. Its sprawling flanks and surrounding páramo
form the Cotopaxi National Refuge, and that covers more than 33 thousand hectares
— or upwards of 90,000 acres! At
base camp, we were able to glimpse the summit through clouds a couple of times,
and I remember thinking, all I have to do
is walk there. I know from
running track that, in my day, I could have covered 300 meters, or just
under1K, in 40 seconds or so. Yet
standing at 18,300 feet of elevation, just 1K below the summit, I might as well
have been looking up at the moon.
The difference, of course is elevation. And high elevation climbing is all
about acclimatization. Ideally,
you spend at least a couple of weeks taking as many high elevation forays as
possible. Just two weeks earlier, however,
I’d been training by surfing and running on the beach in Canoa, a little
fishing village on the Manabí coast.
After nine months living and cycling and hiking from 8,400 feet and
higher, we’d moved to the coast, to sea-level — and thus, I’d forfeited all of
the elevation conditioning I had gained in the previous months. In terms of elevation acclimatization,
it only takes a week to lose what it takes months to gain. This would prove to be a big part of my
elevation problem, or at least that’s my theory. It’s said that some people, regardless of fitness, just
can’t do high elevations. It’s
possible that I’m in that boat as well.
By the time we got back to Andes from the coast, I’d only have two weeks
to re-acclimate and do a few high elevation hikes – none of which was in excess
of 15,000 feet, which is lower than base-camp from which we departed for the
summit. So I may have been doomed
from the start.
Cotopaxi is usually attempted from the north side, but my
friend Pete had connections with the owner of the less popular Refugio Cara Sur
(south face refuge, or retreat). Don Eduardo, whose land abuts the National Park had, picked
us up in Quito in the early morning.
Driving his LP gas modified Toyota Land Cruiser, he stopped once for
groceries, and then drove us up the rutted out road to the Refugio, which sits
at just under 13,000 feet. There we
ate a lunch of chicken soup, bread and tea, and then got outfitted with our
climbing gear: hard plastic boots, crampons, gaiters, heavy shells, helmets,
harnesses, and the indispensable ice-axes. Shortly thereafter, we met Segundo and promptly set off hiking
into the páramo, which soon gave way to the iron-streaked lava-scree moonscape
of the volcano where high camp was situated, just below the edge of the
ice. So we wound up and up from
Quito to high camp, all in the same afternoon.
Before we left the high camp at a little after midnight,
Segundo had asked if we had any extra batteries. Neither Pete nor I had any extras… just one small headlamp
apiece. Oh well, he’d said, like
it was nothing. Segundo had
upwards of 35 summits under his belt on the south face; he knew it like his own
backyard. Well, it was his own back yard. He’d grown up in Latacunga below, on
the shoulder of Cotopaxi. While
preparing soup at base-camp he spoke Kichwa to another guide who was leading a
solo climber from Germany. I
assume they were discussing logistics.
Whatever the discussion, he’d led us, he and Pete and I, roped together,
winding through crevasses, dropping hundreds of feet in some cases, literally
in the dark.
The logic behind the midnight start-time for the summit hike
is the stability of the ice. When
the day warms, the ice becomes more dangerous. The typical game plan then is to summit around day-break,
take a couple pictures, slap some high-fives all around, and descend before the
daylight temperatures warm up the ice pack.
We turned back just as dawn was creeping into the valley
below. As we descended, I noticed
the mine-field of crevasses we’d navigated. “Holy shit,” I said aloud to myself several times. There was one thin spot, especially,
where Segundo had us anchor him with ropes and ice-axes as he crossed a narrow
ice bridge. They put me in the
middle, incidentally, because I was the heaviest by far, and if I went down a
crevasse — the thinking goes — there’s an anchor on either side of me. If I were first or last and went into
the abyss, conversely, there was the fear that I’d drag my two fellow
mountaineers down with me.
Ironically, a big part of the timing for our hike was the
fact that June is one of, if not the best times of the year to attempt the
summit. The weather is the most
peaceful, and the ice is the most stable.
While we were down on the beach, however, just a few weeks before our
anticipated climb, I read in a national newspaper that a Canadian woman was
killed by a massive falling chunk of ice while attempting the summit on the
north face. She was in her early
20s and fit, proving that the mountain doesn’t care who you are – a sobering
reminder of the consequences of high altitude adventures.
By the time I was back in Otavalo, in the Andes, we had lived
in Ecuador for ten months, and despite having to start all over elevation-wise,
I was feeling pretty comfortable getting around. Fuya Fuya Volcano was my local “hill”, my main go-to hike,
and it was becoming familiar with several training hikes. After looking at it for so long and
living just under it — and even circumnavigating it — I’d finally hiked
Imbabura Volcano with Pete at just over 15,000 feet. Still, I wonder how I would have done without living for a
month at sea-level.
Pete shook me awake, and the hammers started in my head
again.
“We have to get down.
Now. The longer you stay up
here, the worse it gets.” He was
right. I’d lost two nights of
sleep, one due to trip anxiety and 0-dark-thirty travel, and one at the high
camp where we were to “nap” from dusk to midnight. The combination of cold (I had a short, badly insulated
sleeping bag) and hurricane-force wind whipping the tarps of the camp, as well
as chronic dehydration, I didn’t sleep for a nano-second. I’d just drifted off for the first time
in 48 hours, and the delicious sensation was seductive.
I crankily roused myself, stuffed my feet into cold-hard
mountaineering boots, slid on my outer layers, gathered my gear, and followed
Pete down the volcanic moonscape trail back towards the paramo and the
Refugio. With each step we
descended, I felt the pressure on my temples let up, and when we got back to
Eduardo’s place, I happily gobbled Ibuprofin like skittles and drank a couple
pints of water. On the walk down,
I began to re-occupy my own head.
Squat purple and yellow wildflowers dotted the trail, and couple of
rainbows even bloomed over the quebradas below
us. What an unearthly and utterly
beautiful place.
By the time Don Eduardo was driving us back down toward
Quito, I was back to normal and grateful, first for being alive and second for
the chance to walk on a glacier.
Cotopaxi and its sister volcanoes Illiniza and Antisana
supply Quito’s 1.6 million people with potable water. But the glaciers are melting. Quickly. Pete’s
lived in Ecuador for ten years, and he’s seen the white line receding up the
mountain. Some scientists give the
dozen or so glaciated Andean volcanoes another ten years before the ice runs
out completely. t’s a sad state, and one that Americans are responsible for
at least as much as Ecuadorians, whose carbon footprints are generally a lot
smaller. Yet it’s Ecuador and the
people of the capital who will have to struggle with some sort of replacement
long-term — and neither gringos nor South Americans, at least in my personal
experience, are good at planning for the long term. Maybe if Ecuador figures it out, they can give California
some pointers.
Back in Vermont, water is still plentiful, and I still take
hikes. But few if any of my mountain adventures around here require climbing harnesses and ice-axes. Camel’s Hump, my neighborhood go-to
hike, always reminds me of a miniature Cotopaxi. Its summit takes me just over 4,000 feet which is a perfectly fine elevation for me. Resting Lion, as the indigenous people
named it, is also conical in shape, though formed by colliding continental
plates rather than uplift. It’s
also much older, having been worn down by the last glaciers that roamed freely
over North America, and finally retreated into the arctic. Unless socked in with clouds, I see it
loom over the valley on my evening commute home from work. And while I only hike it a few times a
year, I often think, all I have to do is
walk there.

The Shell
“Yes! I see something,” she said. “I’m just going to dig right in. Hang on.”
And she did.
She dug right in with needle and tweezers. I gripped the sides of the table, tried to remain still on
the crinkly roll of butcher-block paper they scroll out for each new patient.
After a few long seconds, she said, “Got it!” then dropped
the thing into a stainless steel bowl with a tinny clink. And with that
sound I felt two months of tension release from a wound just right of the ball
of my right foot. The thing, a
little spine of calcium carbonate – half the length of my pinky nail, had
hitched a ride from a South American beach all the way up the east coast to the
Green Mountains of Vermont. Dr.
Hannah came around the table and handed me the bowl. I looked at the little white sliver, and tried to hate
it. But I couldn’t. Finally, she said, “Well, that’s the
last bit of Ecuador in you.”
Mollusks craft their own shells by manufacturing their own
nifty two-step epoxy out of proteins and minerals. Unlike the shells of tortoises, seashells – like the ones
built by clams and oysters for example –
are not
comprised of living cells complete with blood and vessels and nerves; rather,
mollusks sculpt their armored homes out of proteins secreted from the “mantle”
– which comes from the Latin word for cloak, a folded covering around the
spineless little creature. This
“protein matrix” forms the molecular undergirding, and it dictates the
structure and shape of the shell.
Then the crafty bivalve secretes minerals, usually calcium carbonate, to
fill in the hard material, and this accounts for 95% plus of shell
material. For Genus Spondylus, sometimes called the spiny
oyster, this means forming sharp katana-like needles protruding from the center
point, an excellent defense. One
that I stepped right into.
The doctor’s words hung there, the irony unfolding in my
head like a map. We – my wife and
two children – had been back from a year-long endeavor on the equator for just
a few weeks. The surprising hangover
of culture shock would not wear off for months, but this little operation was
the official start of the process for me.
In Ecuador, we had lived in the Andes for nine months of our sojourn. After pulling our children from their
school programs, we had decided to travel beyond the weekend forays we’d been
making. We had spent those nine
months making a home and meeting people – establishing roots. I taught a semester of English in a
little university and my wife practiced massage therapy, mostly on evangelical
gringos. Yet the longer we stayed,
the more obligated we felt to see everything that we possibly could before
returning to the states. In short,
our purpose shifted from inward to outward.
After a few weeks of travel, we returned to our little
apartment in the Andes. Once we
returned, however, we realized that without our children in school, there was
no reason for us to be in the same place for the two remaining months of our
stay. Our sense of purpose had
already hopped a bus to Quito.
Plus our house in Vermont was rented for two more months, key to our
economic survival for the year.
So, as we made many of our decisions in Ecuador, we moved on a whim (and
a little research) to a small fishing/surfing town on the Pacific coast for a month
– to learn how to surf, to experience a new place. The third day we were there, wading out for a morning swim, I
stepped squarely on Spondylus.
For those last two months in Ecuador, I rolled my foot from
outside in to avoid the shooting pain of that little shell. Every once in awhile, I’d try to dig it
out myself, unsuccessfully. Still,
I’d run, surf, bike, and hike daily.
I had to train for a summit attempt on Cotopaxi, an iconic glaciated
volcano south of Quito, rising up over 18,000’. My friend Pete and I had scheduled the climb for August,
just two weeks before we’d return to the states. So I had to move.
And to move, I had to roll my foot. I’d run the beach, five miles a day – in running
shoes. Ultimately, Pete and I were
turned back 900’ from the summit by an ice storm and altitude sickness, but my
shell also made it to 17,000’.
Back home at sea-level, I immediately set to work: gardening,
cutting brush, putting up wood for winter – and painting houses, something I’ve
done for twenty-five years now.
Between school years, I paint – which helps to support a bicycle habit
I’ve developed. I’d hiked and run
and cycled with that shell in my foot, but finally having to stand on an
aluminum ladder, on the balls of my feet concentrated the pain in new
ways. I knew I finally had to go
see a doctor. I kept to the idea
that it would work itself out, but it didn’t. It wasn’t going to come out by itself on a wave of puss and
blood – it needed a midwife: Dr. Hannah.
Of course, Ecuador is in me still, long after the physical
effects of a spiny oyster shell wound and a greater capacity for absorbing
oxygen at altitude – any place a person spends a year is going to be in him,
especially a foreign place. The
word foreign is derived from the Latin word fores
or door, after all – it’s anything outside your door. Experience is getting out the door, wherever it is, and
growth. Like the formation of
seashells, which must continually expand outward to accommodate the growth of
mollusks, experience helps us expand out from our centers. And the more we get away from
ourselves, the more we understand when we return.

Skin Game
“It’s the best kind of cancer you can get,” she says hanging up the phone. I don’t like “best” and “cancer” in the same sentence. She knew it wasn’t going to be good news when the clinic left a message to call back. We were camping in a state park in southern Vermont. All of the little pressing needs of sleeping in tents and living off a picnic table swept us back into the present.
More people have skin cancer than all other types of cancer combined. Rates of melanoma -- the worst kind of skin cancer -- have gone up 200 percent between 1973 and 2011, according to acting US Surgeon General Boris Luchniak in a recent report. This type of cancer kills 9,000 people a year. Despite the alarming rise, skin cancer is both treatable and preventable.
Later, my wife made the appointment to have the growth removed. Melanin-challenged, I like to call her. Sun-deprived Northern Europe runs deep in her genes. She sees a dermatologist regularly who’s mapped and measured the little constellation of moles on her back. She’s supposed to use wide-brim hats and sunscreen. Sometimes she forgets the hat. I nag her about hats all the time.
When I was a kid in the late 70s, we spent all day getting baked by the sun at a pool. You burned once in the spring, then spent the rest of the summer in a speedo, brown as a bean. My mother read crime novels while sunbathing on the patio. Now we make our kids wear swim shirts, and we slather them with a layer of 50 sunscreen.
Just under 5 million people were treated for skin cancer last year, so most cases of skin cancer are treatable. But it turns out that a whole lot of them are preventable as well. Aside from blocking the sun from hitting your skin with shirts, hats, and screens, you can stay out of tanning beds.
The use of tanning beds is the American cheese of the beauty industry. Both are ultimately fakes; while they might look tasty at first, they leave you unnourished; and they both give off an unnatural orangey glow. Thanks in part to the popularity of tanning beds with particular demographics, “over the last three decades, the number of people with skin cancer has grown higher than that of all other cancers combined.”
Among other findings, The Surgeon General’s report concluded that tanning with electricity contributes to two thirds of the new melanoma cases each year, over 6,000 cases. Additionally, skin cancer is the most widespread type of cancer among youth and young adults. And so they’ve taken some corrective action by banning the use of tanning beds for people under 18.
The Indoor Tanning Association -- yes, there really is such an organization -- disputes the link between melanoma and fabricated ultraviolet light. If tanning on a tanning bed is American Cheese, the ITA must be Kraft.
Like hats, you can wear them or not. Hey, it’s a free country, right? I can go on down to the store and buy myself a pack of Marlboro Reds if I want. Maybe a better analogy for indoor tanning and the ITA is Philip Morris.
“Proponents of sun avoidance always exaggerate the risks of exposure to ultraviolet light in order to get the attention of the public, the media and the government,” the association said. But let’s just take a look at the motives here for a second: tanning beds are about turning profit by appealing to vanity, and the SG is about promoting health by appealing to common sense.
As for me I’ll keep trying to promote common sense in my family: I’ll keep packing the hats.

MTB in the VT
At the top of the hill, I slide my fingers into a fresh, dry pair of gloves, flex then ball them into a fist to get the fit right. I cinch on my helmet, slide my glasses into place, and swing my backpack onto my shoulders. My bike leans against a small hemlock. It’s a full-suspension rig, which means that both the front and the rear-end have shocks (with over 5” of “travel”) to absorb and smooth out the roots and rocks of the trail. It has hydraulic disc brakes to control speed with a finger or two, and the seat-post is also on a hydraulic lift so that I can drop it low on technical descents, get way out over the rear wheel for stability and flow. I lift the rear-end to check for wobble, but it feels solid -- so I mount up and push off into the first feature series of the descent: a rocky spine of schist which drops off into to a series of switchbacks cut into the hill with hand-dug berms. I let go the brakes and let the bike run into the corners. It hums right over roots and small boulders. I’m a kid again. A boy in the woods on a bike with a grin on his face looking down the line of the next dirt jump.
And that for me is what it’s all about. The aerobic exercise is good, and the adrenaline is fun -- but getting back to the kid in the 43 year-old me is more than just exercise. It’s a near daily purification ritual that involves getting dirty. The thing is, I have a few more resources than when I was twelve, and my toys are a little more sophisticated. While the main idea is still rolling on two wheels, Mountain biking has come a long way since the late 80s when off-road specific bicycles first became popular -- a long way. Even if riders resist it, the sport has grown up.
First developed in the late 70s, mostly in Marin County, CA, the sport of mountain biking began with the old newsie “klunker” and Mount Tam. The pioneers of the sport -- some of whom are the empresarios of today’s industry -- began with bikes of the 50s because they were solid, steel, heavy, and most importantly: durable. These guys, and some women too, would take these klunker-beasts to the top of Mount Tamalpais and then “race” down. Allegedly, first prize was often “smokable”. As they began to break theses bikes, they began to innovate. As the frames were too heavy for climbs, they began to build more durable off-road frames. Easy as that, a new sport was born.
But it would take another couple of decades for the bikes to get really burly -- a lot of them even look more like off-road motorcycles than they do their now distant “roadie” cousins. And they certainly owe some of the technological advances to the motor-sport as well, namely hydraulic suspension, hydraulic disc brakes, and big, fat knobby tires. Time after time, I am amazed at what the technology has allowed me to do. Sure, I can ride the same trails on an old “rigid” bike with no suspension -- sometimes I do -- but with the new version, I can tear down the trail at twice the speed, huck my 210 pound self off of ledges four or five feet above the landing, land with a gentle ka-thunk, and flow on.
Not only has the bike evolved, but the surface on which we ride has been significantly and mind-alteringly improved, just in the last six or eight years. In the “old days”, we either found old logging roads, fire-roads to ride. We made “rake and ride” trails -- that is, we raked off what we wanted to ride, and then we rode it -- over and over until it was officially a trail.
Now trails are designed, and they use some sophisticated tools to get the job done. Trail builders even plan and use math! They scrape off the first layers of earth, down to the clay if possible; they rake it out, fill it with rock that drains, and pack it back in. They build huge earthen walls called berms that are specifically calibrated to let a bike tear around a corner, 180 degrees, downhill -- without braking! And uphill climbs are now so full of switchbacks and contour-following lines that it hardly even feels like you’re climbing a hill. These designers have learned to work with Vermont hills so that it’s all about “flow”. They design and build trails that wind through the woods and mesh with the environment so well that you forget the massive amount of work that went into them.
But a lot does go into them. A typical mountain bike trail in VT costs about five bucks a foot, on average. This cost comes from machinery, often full-time staffers for various areas, and materials. VT is wet, and it takes some decking and engineering to build over some of low areas. We used to cut trail at night, without permission, but organizations like VMBA (VT Mountain Bike Association) coordinate projects with private land-owners and public lands. This organization takes infrastructure. Maturity.
Vermont has become a Mecca for mountain biking in the Northeast with hundreds of miles of these bike-specific single-track trails. When I go to several of my local spots -- and I’m lucky to have a dozen great trail networks within a 30 minute drive -- there are always cars from Massachusetts, New York, and especially Quebec. These have become “destination” riding centers.
It’s easy to take things for granted when you have it good. I don’t though, even after twenty years in Vermont. I did my time in the flat, tree-deprived, soybeans-and-corn midwest as a teenage pent-up ski bum and road biker. I know Vermont is weird; we like it that way. We do things here like ban roadside billboards and offer free, universal health-care up to age 24. We know our neighbors, and we know we can depend on them in a pinch. Sometimes we even work on the neighborhood trails together. Mainstream doesn’t count for much in the 802, and that goes for “fringe” sports as much as anything else. The fact that I can hop on my bike, spin out my driveway for a good ride on mountain bike trails keeps me grinning like a kid.

An Uphill Battle: Coming to Terms with the New Policy
Coming up the last stretch of Antelope, I knew the rest was just a kick and glide to the Stark’s Nest. Putting my shoulder into the door, I opened it, kicked my leather boots on the step a few times to knock off the snow and stepped inside to double up my fancy new 40mm Pomoca mohair skins. I shook off my Andean Toque and glanced out the window at my sweet 215 Tua’s resting against the rail, sporting revolutionary bindings (with a heel-throw!) and a state-of-the-art capped top-sheet The snow was gently settling in on Chute, beginning to fill in the nooks and crannies.
I know, I know -- that guy totally still skis Mad River. There’s plenty of him lurking in the hills today. But 18 years ago, he was pretty much the only guy hiking for pre-season turns. The sport of backcountry skiing then was a tiny niche occupied by Dickie Hall and twelve other guys. Now the Rat pull-off is full by 7:30 in the morning on powder days, and sleek people with super-light Dynafit set-ups and blade sun-glasses are storming the mountain in hordes.
Part of it is the gear, for sure. AT equals access, and the stuff has gotten really, really good. No more sacrificing weight or stiffness of boot or compressing springs with every step -- ski-hikers of all varieties have never had it so easy. And so it makes sense that they’d want to ply the frozen waters of the Legendary Stark Mountain, whether a regular pass-holder or weekend warrior hitting any number of closed areas.
The other reason for the increase in uphill traffic at pretty much all of the New England ski areas is snow -- or rather, lack thereof. Yes, I hate to say it, but the New Norm has all of us who enjoy sliding on frozen precipitation a little bit cagey. Last season was great (except for January, which we won’t talk about) -- but if you remember the lean year of 2011/2012, and you happen to enjoy earning your turns on Stark Mountain, then you would have seen a HUGE increase in uphill traffic. While the surrounding hills were brown, MRG’s mountain ops were working their magic by grooming in and preserving the snow that we did have. The upshot: more people were taking to closed areas to get their backcountry jollies.
Who can blame them? Certainly not me. I joined them regularly. Like many, I absolutely depend on Stark Mountain for my gym membership, my therapy, and my adrenaline fix.
While famous for its terrain and schools, Mad River is not necessarily known for being on the cutting edge of the industry. (I’d wager that there are more people skiing MRG in and on gear they bought in the 80s and 90s than at any other ski area around -- which, in my humble opinion, is totally awesome.) Still, with most of the ski resorts in the US developing uphill traffic policies, it was high time for Mad River to address the issue, simply by virtue of the increased number of people doing it. And like most of the neighboring areas in No. VT, they have been batting ideas around for a couple of years now.
To me, common sense reigns in the new list of dos and don’ts. Most importantly: you can still hike Mad River -- though it is not patrolled during off-hours and seasons and not recommended. Additionally, Ops report a growing number of people trailing the groomers in order to suck up the sweet-fresh corduroy. Not my thing personally, but you can see how this would be a safety issue since a skier can very well catch a moving Cat if s/he wants to. There are also growing numbers of people who want to skin while the lifts are turning, and there have multiple close-calls between downhill skiers and uphill skinners on blind corners. A good debate has emerged on whether or not there should be a designated uphill route (yes, please!), or whether or not passes would be required for climbing (they probably should -- you have to buy a pass to snowshoe). But for now, simplicity takes precedence. The antidote to your ski-jones is pretty straight-forward: don’t ski when the lifts are turning, and stay away from the mountain crew so they can work their magic.
The policy was coming, no way around it. There are just too many people trying to get on the hill these days, and it’s high time that Management at Mad River came up with a responsible, common sense plan to deal with it. And I believe they have. There’s the safety thing, and frankly, the liability thing. I count myself among the many BC skiers who do not like to be told where they can and can’t go -- but at the same time, I can’t blame Mad River at all for getting with the times and setting some reasonable ski boundaries. The new uphill traffic policy doesn’t really change anything for the typical skinner, the vast majority of whom are pre-season or post-lift operators who will continue skinning obliviously compliant with the new regs. Heck, snowboards have never been banned from the mountain -- just from the lifts. So whatever you slide-fix, check the glue on your skins, get ready for the next (pre) season, and see you on the hill!
