This winter’s snowpack has been described in the avalanche advisories as bad, poor, weak, unstable, dangerous, and tricky. The reason is simple: the early snows in November transformed into sugary grains of angular facets that do not bond to each other and are exceptionally weak. These facets are the foundation of our snowpack. This foundation is weak, crumbly and poorly supports December’s snowfall.

The snowpack is a record of weather events that take place during the winter.  Heavy snows, wind, even long dry spells, help to create unique layers in the snowpack. The order in which these weather events occur determines both the structure and stability of the pack.

The first turns of the ski season can be dicey: the snowpack is thin, avalanche skills are rusty and we are itching to get out and play. This is a recipe for avalanches and injury, not success. Fortunately, our stoke and motivation can make us ready for better, deeper times. We wax skis, tune sleds and rip tags off new gear to get ready, but we are not done. What causes avalanches? You! More than 90 percent of fatal recreational avalanche are triggered by the people involved.

Snowmobiling in the mountains is risky business.  Once a rider leaves the groomed trail and enters the uncontrolled and unpredictable realm of the backcountry, they immediately become exposed to a variety of hazards.  One of the most inherent risks a backcountry rider confronts is the possibility of triggering or being caught in an avalanche since avalanche prone terrain often offers exciting riding opportunities.

Spring skiing can be some of the best of the season. Good snow coverage, warmer weather and more predictable snow stability (at times) can lead to unmatched conditions. While spring skiing can be the best, it can also hold avalanche hazards not encountered during the colder parts of winter.

As snowpack and weather transition into a warmer and wetter spring pattern, there are a number of avalanche variables to pay attention to.

The snowpack changes from year to year, even day to day but, the terrain on which snow falls remains constant. Understanding and recognizing avalanche terrain are critical tools for safe decision making in the backcountry.

During stable snow conditions, riding in avalanche terrain is safe and acceptable. When snow conditions are unstable, avoiding steep slopes and avalanche run out zones is key to avoiding avalanches.

Avalanche information can sometimes be overwhelming. Without becoming a snow scientist, recreational riders can take a few simple steps to become better educated in avalanche awareness. During the summer of 2013, the International Snowmobile Manufactures Association, Canadian Avalanche Center and USDA Forest Service National Avalanche Center collaborated to produce a simple yet effective avalanche safety messaging system for snowmobilers. The messaging system consists of five bullet points.

The Class

One night in 1981 Doug Richmond and Tom Pratt decided to offer an avalanche class at Montana State University for both students and people living in the community. Seven nights of lectures for $7. At the time a beer was a dollar, and they figured each lecture was worth a beer.  Now, 33 years later, we only charge $30. The class has four lectures over two nights followed by a field day just out of bounds at Bridger Bowl which has been a supporter of the class from the beginning.  In the last ten years, we have taught this class to more than 3,000 people. It is called Introduction to Avalanches with a Field Session.

As an avalanche forecaster and educator I pay close attention to teaching the recreating public about heuristic traps, aka human-factors, and their role in avalanche accidents. A powerful voice is Powder Magazine’s riveting five-part Human-Factors series which did a great job of pointing out those traps.
