From the time snow crystals fall from the sky to time they melt in the spring, the shape and structure of each crystal never stops changing. This is known as snow metamorphism.
Snow metamorphism determines if individual snow crystals are rounding (becoming stronger) or faceting (becoming weaker). The relationship between snow crystals ultimately dictates what kind of layer, strong or weak, is formed. The interaction between individual layers determines snowpack stability.
For many resort skiers, the word “sidecountry” has become a standard definition of backcountry terrain adjacent to a ski area. Usually the acreage on the other side of the boundary is administered by the US Forest Service and the ski area becomes a convenient jumping off point to access public lands. In the last few years skiers have overwhelmingly embraced this access as the in-bound crowds ski up new snow at a ferocious pace. Untracked powder is a dwindling resource, an addictive drug, and access gates are the needle in a vein to a quick fix.
The third week of December provided some valuable avalanche lessons when three people in two separate incidents triggered and were caught in avalanches near the Bridger Bowl boundary. In both cases the parties exited the ski area into the backcountry. The first incident involved two highly experienced skiers on Saddle Peak. Like they have done for years, they rode the Slaschman’s lift and hiked to the top of the peak. The skied at the same time, but had some distance between them. A few hundred feet off the top one skier triggered a slide on a thinly covered, rocky area and was caught.
I never thought I’d be concerned about my electronics while cruising around the backcountry, but I am. Carrying a cell phone, satellite phone, GPS, avalanche beacon, SPOT Messenger, and a VHF radio means my electronic signature rivals a high tension power line. I hope I don’t have to start lugging around a car battery to keep everything powered. Most people in the backcountry are not as wired as me, but a smartphone and beacon are staples for most backcountry travelers. The beacon is a literal lifeline, the most important piece of electronic safety equipment we carry.

Snowmobilers die in avalanches every winter, killed by trauma or suffocation, an extremely unpleasant way to breathe your last breath. In the last 10 years 93 snowmobilers in western America have been killed in avalanches. This is no surprise. We love to ride steep, open, mountainous slopes in avalanche terrain. If you play in the lion’s den you may get eaten, but as riders we don’t have to go into the den when the lion is hungry.
The day dawns cold and clear with a foot of fresh snow and the promise of incredible powder riding. At the trailhead, the surrounding landscape sparkles like a field of diamonds and the anticipation of a magical day in the mountains builds.
Sled covers are hastily removed and the machines are fired up - the smell of exhaust fills the air. Feeling confident about preparations, members of the group do a quick gear check and then hop on their machines, pinning their throttles towards the backcountry and a day of powder riding.
Blue ice clings to canyon walls, creating a colorful contrast to the steep rock faces of Hyalite Canyon. Climbers inch their way up the frozen surface with axes and crampons, many having traveled from around the world to experience this world class venue.
We just wrapped up our 23rd season at the Gallatin National Forest Avalanche Center, one of the best winters ever: lots of snow, many days of good stability, and no fatalities. It has been nine years we’ve had this combination.
