Freedom of the snow


The invention of skiing did not wait for the invention of the groomer. Skiing developed in areas where it made sense, where the combination of terrain and snow type led to this device that slides through the snow rather than plodding on or in it. All of this happened so long ago that we have only some uncaptioned artifacts of the time, not explanatory accounts of the design development process. It's a pointy board. The front end curves up. Take it from there.

The boring cousin of the ski is what we now think of as a snowshoe. But the skiers of the 19th Century called their skis snowshoes. In written accounts of the time, you will see that term. Fridtjof Nansen used it in Farthest North when referring to the skis used by the expedition. Skis and snowshoes are answers to the same basic need: traveling in a snow-covered landscape with the least effort required.

Least effort may seem like an inappropriate term when bulldozing up a steep slope with either device on your feet. And the device we now call snowshoes never gives you the dividend of glide. You pick them up and put them down.

When the trail was the road, the winter trail would be packed by all of the travelers using it, from the buildup of the snow pack, through the heart of winter, all the way to the thaw. The thaw would isolate people much more than winter did, because travel would be exhaustingly slow or outright impossible as the winter's accumulation turned to a mire of granular soup. But during the heart of winter a traveler could branch out onto lesser-used trails, or through areas with no trail, using the versatile human-enhancing devices common in their culture. Later, when the ski had been introduced to many areas outside of its native range, it was added to the available toolkit. By then, of course, the Industrial Age was advancing, and travel by machine was becoming more and more of an option. But the initial diaspora happened early enough to make skis a practical part of life in areas without developed road systems.

All that was a long time ago. Almost no one now needs to depend on skis to get around. It's a lifestyle choice. You might manage to build yourself a life in which the ski becomes a necessary, practical tool, but only because you chose to go that way. For the rest of us, it's a matter of aesthetics. But that can cover a wide range of considerations.

Exercise is good. Exercises that demand a degree of coordination help to keep those parts of the brain engaged. One way to maintain balance is to use your balance. But long before one needs to think of the geriatric aspects of skiing it also offers unmatched versatility in dealing with a wide range of snow conditions.

Let's talk first about where it doesn't work well at all. Ice is the nemesis of skis. You can get ski crampons, but they're not as effective as a snowshoe with teeth on the bottom at dealing with crusty snow and ice. If you found yourself facing a limited area of iciness, or you had to extricate yourself from the wilderness after an ice storm blighted your multi-day backcountry ski tour, you would have to figure out how to use whatever tools you have at the time: metal edges, ski crampons, alternate footwear. It's all a matter of what you want to plan and carry tools to deal with.

The deeper and softer the snow, the larger the "boat" you need to float on it. You may be floating pretty low in it, on skis or snowshoes. But a touring ski is designed to plane upwards, whereas a snowshoe has to be lifted and set down in a more deliberate fashion.

All winter travelers in the human-powered era would look for conditions that were firm and fast. Even in a modern world, recreational snow travelers prefer to have a trail that has been packed and smoothed. This opens the door for such totally grooming-dependent users as fat bikes. And for skiers there's such a thing as too hard a trail. A well-used hiking trail that has been through some thaw and freeze transitions can be like undulating porcelain. A $250 set of snowshoes with a crampon, or a $250 set of studded tires on a $2,000 bike might find the going good on the porcelain trail. A ski not so much. Of those users, only the bike would be completely dependent on the trail, though. The ancestral snow devices -- skis and snowshoes -- have the option to bushwhack much more freely than the bike rider can ever consider.

When we got an early winter delivery of about 5 inches of snow here, I went out on my old faithful 200cm long, 60mm wide skis, with my rejuvenated 75mm boots, to slide around the woods. Parts of the state got ridiculous amounts of snow, upwards of two feet in places. Too much at once can be hard to manage, even for people who like snow and might make their living helping people to play on it. Five inches was just enough to cover most of the irregularities on my crudely defined trails. Much of the forest is open enough to make a trail more of a technical formality than a necessity.

The steeper slopes farther up the mountain -- or even at the back of my own patch -- need more snow to make descent controllable. It's never safe. You can move extremely methodically to reduce the risk of a mishap, and find yourself overtaken by darkness because you took so long to get down. This is highly unlikely when the total distance to home is less than 1,000 feet, but becomes a distinct possibility when the slope you can reach higher up has become a complex bushwhack including old-growth forest, steep, rocky slopes, new, large clear cuts, and dense thickets of saplings. Depending on when you start out, you have to watch how much time you expend on each part of the journey. That's true anywhere you go.

If you're unsure of snow conditions where you're going, the conservative choice is the snowshoe. You give up on glide, but you know you'll be able to trudge reliably. If you know that snow conditions will allow for it, and you have the skills and equipment, skis offer you the most freedom. Gliding liberates you from friction. Gravity becomes an asset and a plaything.

Nordic got run over by a fat bike

Think of the tune, "Grandma Got Run Over by a Reindeer."

Cross-country skiing is dying, killed by climate change throughout its range. This is happening more rapidly in the lower 48 states of the USA than in Scandinavia, but all over the Nordic racing world events are being held more and more on manufactured snow. And that's only possible if temperature and humidity -- not to mention budgets -- allow for enough snow to be made and distributed over a trail system.

Racers will put up with incredible tedium to develop and maintain their fitness, and then submit to torture on a challenging course. Any skier might prefer more variety and free range, but the addicted competitor will go around and around and around and around and around and around a kilometer or two for the sake of race-ready strength and technique. They are not the majority of cross-country skiers, but they are the ones who will spend the most money on it per capita.

Tourists make up the vast majority of the small portion of the population that still skis cross-country. Tourists have a variety of motivations, fitness among them, and cheapness strongly evident. That's a major reason that the ski industry as a whole dislikes them. Frugality generates little profit compared to addiction.

It takes money to run a trail system. Cross-country ski centers have to maintain trails in the off season and groom them in the ski season. Since the widespread acceptance of skate skiing in the late 1980s and early 1990s, that calls for a machine that easily costs more than $100,000.00, requiring fuel, maintenance, repair, and a skilled driver. Larger areas need multiple machines and drivers. Any area also has to maintain the trails themselves in the face of erosion, encroaching vegetation, blowdowns, and abuse by unauthorized or destructive shared uses.

When Surly introduced the Pugsley as a complete bike in 2011, it launched the category as something people could buy "off the shelf." Our own shop and touring center pondered whether the bikes would make a worthy addition to our mix of users as a way to weather the increasingly irregular winter conditions that the changing climate had been bringing us. However, our early experiments discouraged us from trying to blend skiers and bike riders on a single trail system.

When the bike industry tried to make fat bikes the next big thing around 2015 there was an explosion of interest that looked like it might turn into a bit of a boom. But as the browsers browsed, most of them chose not to invest upwards of a thousand bucks in yet another bike. Various media outlets ran weirdo-news features on the nutty people riding goofy bikes on the snow(!), but the curiosity was not matched by significant sales. Meanwhile, in the bike industry's usual fashion, they mutated the bikes rapidly, challenging consumers and shops alike to keep up with the need for newer and ever more expensive tools and parts.

Once the tool of intrepid, self-reliant adventurers, fat bikes seem to have attracted a demographic that might view itself that way, but often presents itself as entitled whiners. Our small touring center has seen a determined assault by a handful of riders who have looked for any possible leverage to force us to allow them onto the trail system. They have also proudly posted pictures on social media of themselves poaching the trails. I believe that it's become an obsession with them that means nothing more than another notch on their bedpost. Their own representative has stated at meetings that most riders aren't looking for a 20-foot-wide trail like an interstate highway through the woods. Minimum width for a skate groomed cross-country ski trail is about 12 feet, but much more would be needed to accommodate bike traffic and ski traffic in busy periods.

Will there be busy periods? Between the decrease in natural snow and the daunting expense of buying a winter bike, both sports remain a small percentage of winter recreational activity, far outstripped by motorized activities and downhill sports using motor-driven chair lifts. So what happens next? People want to find a place that has bought a rental fleet of fat bikes for them, on top of expanding the trail system for this new user group. How many touring centers can afford to put together a fleet of expensive and complex bikes and maintain them in readiness for whoever might want to try them out? This situation is being forced on the cross-country ski business by an alien culture.

This isn't just as simple as the ski versus snowboard debate. It has elements of the skate versus classic debate, in the different ways that the user groups occupy space on the trail and flow through the terrain. Having skied both classical and skate, I can tell you that the two techniques can come into conflict when skiers of each type converge. Now throw in some bike riders. The skate skiers can at least bring their skis parallel and double pole through a pod of slow tourists. Skiers don't have 31-inch-wide handlebars. And riders with 31-inch-wide handlebars can't reduce that dimension for a courteous minute or two, even if they might want to.

Skiers also have their feet on the ground. If a skier has to stop, it's not that hard to step off the trail, or at least move to the very edge of it and stand in a way that leaves plenty of room to pass. It's not as easy when you come off the pedals and either need room and time to dismount or need to waddle along straddling the bike. Also, your 5-inch tire at 8 psi might not make much of a mark, but your big clodhopping feet do.

Life is full of inconveniences. We have to make allowances for each other. Motorists hate having to accommodate bicyclists on the roads, and make many arguments about the differences in speed and maneuverability between the various size motor vehicles and the ones being pedaled. The difference is that all of our taxes pay for the public right of way, and that we all have a right to travel freely. A trail system is not the public street. The idea that cross-country ski trails should be coerced into admitting fat bikes is fairly recent even in the short history of fat biking itself. The pioneering riders used things like snow machine trails, just as their ancestors did, way back in the 1990s, when winter riders on the mountain bikes of their era either bought or made studded tires to go ride on those trails or on frozen lakes, woods roads, and other open venues.

The group of fat bikers that set its sights on the trails in Wolfeboro saw trails already groomed and looked for a way to commandeer them. With absolutely no respect for the decades of time, effort, and non-governmental investment that went into the trails, they seized on a flimsy legal possibility to force their case. Since they opened this can of worms, other user groups have tried to present themselves at the same loophole to be allowed to walk their dogs on the trails. The grooming is not done by town employees using town equipment and town funds. If a dedicated non-profit organization had not devoted itself to maintaining the trail system in town, that system would not exist, and we wouldn't be having this discussion. The fat bikers would be riding on whatever was open, just like the poor kids do in towns that don't happen to have a well-established and once-respected ski association.
