Nosehair Update

Since my post on January 10, nosehair-freezing cold finally did put in a brief but dramatic appearance on February 3-4. It even spawned breathless news broadcasts and articles because the Mount Washington Weather Observatory recorded a record-setting wind chill factor.

Wind chill is not temperature. Block the wind and it goes away. If you are wearing sufficient insulating layers and a windproof shell, the effect nearly vanishes. I say nearly, because most of the time our bodies and our buildings are losing a little heat even when snugged up adequately for average conditions. Outside of the enclosure, a little thermal gradient fades out from us, reducing the rate of heat loss from where we want it. Wind whipping over this strips it away, removing the invisible insulation we gained from it.

Winter cyclists have to deal with wind chill all the time, because of how we generate our own, rolling along at whatever speed we're doing. Cold-weather cycling is one of the hardest activities to dress for, because the rider is generating heat through exertion while flying along through the cold atmosphere, cranking up hills and coasting down them, with an actual wind that may come from any angle, interacting with the apparent wind created by forward motion.

I don't know anyone who tried to go for a ride on Saturday, when the temperature started out around 12 to 15 degrees below zero F, with a wind gusting over 30 most of the time. In our shop, with the furnace cranked, we spent most of the day with an indoor temperature from 52 to 54 degrees F. We finally got almost to 60 by closing time. The building was constructed in the 1860s, I believe. The walls were thin, and insulation nonexistent. In a Nor'easter, we can feel the wind actually blowing through the back wall. On Saturday, the wind was westerly enough that it didn't come through directly, but it still stripped escaping heat away from the outside. Some insulation has been added in modern times, but the thin walls mean that there's not enough space for much.

The next day, the temperature climbed steadily to the upper 30s and only dropped to the 20s. Today it got even warmer, with a bit of sunshine. Winter reverted to the temperature range it had stayed in since the season began.

The cold stab did get Lake Winnipesaukee to freeze all the way over, but I would not recommend going out on the new ice. "Ice in" is merely a technicality.

The series of storms that finally brought enough snow to open the cross-country ski trails also brought rain and wet snow in a diabolical combination that produced a thick crust on top of loose snow underneath. The crust can't support a person on skis or snowshoes. It varies in thickness so that the way it breaks from one step to the next makes snowshoeing a laborious series of stumbles as the edges of the shoes catch on the crust. On skis, the crust still breaks, and neither the crust nor the loose snow offer any grip. In bare boots, a post-holer discovers that the snow is deeper than you might expect, with the meager accumulations and long warm spells. On the groomed trails, the cover is barely adequate. Grooming reduces the snow depth and steadily wears it away, while the thinned surface is more vulnerable to the sun heating the dark earth.

The roads don't exactly beckon, but they do offer a passable option for a pedaler who has not invested in a fat bike with studded tires. Some snow machine trails are probably firm enough for a regular mountain bike with studded tires. I prefer and recommend changing to weight-bearing exercise for part of the year, but even the less helpful exercise of pedaling is better than none at all.

I don't have time on a workday to fit a ride in at either end of it until commuting season, and my days off seem to get eaten up with all the things that I don't have time to do in the margins of a workday, so I'm just deteriorating steadily until the daylight gets long enough to start getting base mile rides. I salute all you people with the strength of character to ride a trainer on a regular basis. I do not envy you in the least, but I respect your gumption. That's a lot of sweat and bike abuse.

It ain't really winter 'til your nose hairs freeze

 Every time we get a weak winter, I compare it to my memories of 1990-'91 and 1991-'92, the two that stood out for late arrival of snow, little accumulation, and overall mildness. The winter of 2005-'06 was another disaster for winter-based industries in New England, in which I recall doing more riding than skiing or other winter-specific activities. But a check of the records shows that in all of those winters we had at least some short periods of usable winter, and a few nights of nose hair freezing cold.

Your results may vary, but I find that nose hairs begin to freeze as the temperature nears 0°F, and intensifies as the temperature continues to drop. For instance, someone misread our digital thermometer and told me that it was 17°F one morning, but I knew as soon as I walked out and breathed in that it was 1.7°. 

When I'm stacking firewood into the shed in the summer, I often think about what conditions will be like when I reach that part of the pile during the dark and frigid months. I can recall many images of shivering under the cold LED light in the shed, pulling down an armload of logs to keep the wood stoves cranking against the implacable cold of the universe, toward which our end of the planet is pointed during the northern hemisphere's turn to aim away from the sun. This winter, just about every trip to the woodshed has been more like late March, or even April, except for the sun angle and day length.

I could post this as a ski column on Explore Cross-Country, but there is no skiing, and there might never be. It should surprise no one that this is the warmest, wettest, least useful winter on record, at least until the next one. We're already getting calls about bike service, not from winter riders, but from people who want to get a jump on their spring tuneups. We still have demand for ski services, so we don't want to reconfigure the workshop for grease, but we may need the income soon. It's still too early for full bike shop efficiency, so the wise rider will wait until at least mid-March, but that could change if winter-specific demand dries up.

I did notice in my training diaries from the 1990s, that I took more opportunistic rides back then. The training diary is also my daily quick summary of weather conditions, which I started adding right around that time, to give my other activity entries more context. Now I find that I really miss the hour or so that I carve out for a ride or a hike, when I have so much other stuff to get done on a day off. From the perspective of age, it seems that the people who get things done are the ones who long ago sacrificed their health, and fitness to the priorities of work. It shouldn't have to be that way, but any better way takes too much thought and care for each other's well being, to make sure that anyone who wants it can have a balanced existence.

The other argument against too much riding is that a rider needs weight-bearing exercise for bone density, and to use the body in different ways that relieve the muscles and joints from the limited range of motion provided by pedaling. You can do weight training, and definitely should stretch in some way, but for the unscientific trainer it's easiest to go do something else. Yesterday, I hiked up the mountain behind my house. I probably won't do it again, because the logged areas are now choked with brambles and sweet fern, and the uncut swaths are filling in with bushy little saplings flourishing because so much sunlight can get in. With decent snow, the brambles and sweet fern are at least somewhat covered and separated by it. Yesterday, I was either wading through the thorns or pushing through the beech thickets to try to gain a few yards on the remnants of the old forest floor.

Because I started late, I did not gain a summit, only one of the intermediate steps that offered a view westerly. To the north I saw that Ossipee Lake is not fully frozen. That is not a deep lake. I know that the big lake, Winnipesaukee, isn't frozen shut, but it is deeper and much larger, requiring a longer, harder freeze. Even giant mud puddles like Province Lake had such thin ice that the ferocious winds of the storm on December 23 broke it all up and piled it on the leeward end, where it refroze into a surface useless for skating. I remember a hike in about 1997, on a small range just over the border in Maine, from which I saw the startling blue of Sebago Lake, unfrozen in a landscape of white. We did have some snow that winter, although as climate change really started to sink its claws into the region, the weird sight of open water provided a warning to the few who cared to acknowledge it.

A native of the area used to say that he hadn't noticed much change in the climate, even up to a couple of years ago, but he has been pretty quiet about it recently. I doubt if his nose hairs have frozen any more than mine have, even if he does live in one of the colder little valleys. And, as a logger, he knows darn well that the wetlands haven't firmed up to allow the normal amount of winter cutting.

No matter how much the temperature warms, the sun angle and day length won't change. There will be more losses than gains, from many economic sectors. People have already reported ticks. Various unpleasant insects are expanding their ranges. The purifying freeze, as hard as it might feel at the time, serves a purpose for the overall health of the ecosystem. Unfrozen lakes in winter warm sooner and reach higher temperatures, aiding things like cyanobacteria, which ruins summer recreation after a warm winter ruined that season's recreation. Cyanobacteria can kill your dog. And it's not that great for humans.

We're only at the beginning of winter's July. There's plenty ahead. Averages are made of highs and lows, so we could get slapped with a little cold snap. The longer it takes to get here, the harder it will bite, because we can't help instinctively feeling like spring when the temperature mimics it. As the sun launches more and more steeply up the morning sky, the first half of a mild day will make you forget how much winter still lies ahead, until the instant shift to late afternoon light reminds you. The sunset is getting noticeably later, but it darn sure isn't late.
