Week September 21 - September By digging a snow pit or profile , scientists can look at the composition of different snow layers that formed during a season, sort of like looking at the layers of a cake.
Canadian Geotechnical Journal
The size and shape of the snowflakes in each layer provide clues about the weather events that occurred: big dumps of snow, drought, rain, a hard freeze, or loose, powdery snow. Larger, looser snow crystals are weaker , because there are fewer points they can touch to interact with the other snow layers. The interaction of the snow layers can help predict the chances of an avalanche.
He emphasizes that conditions can change rapidly with the weather, and this can be deadly. Slopes shaded from direct sun stay cooler, preventing bonding between snow layers and leading to more avalanches in cold conditions. Conversely, during the spring, sunny mountainsides have a higher risk for avalanches because of rapid warming and melting.
Precipitation type and intensity, temperature, wind, slope steepness and orientation the direction it faces , terrain, vegetation, and general snowpack conditions can influence whether and how snow moves down a slope. Moving across the terrain, slight changes in slope or how the mountainside is oriented towards the sun can create drastically different conditions.
The Forest Service runs 14 backcountry avalanche centers in the United States to provide information for people recreating in snowy wilderness areas. Forecasters use four main elements to describe conditions, assign a danger level , and help recreators make the best decisions in the backcountry.
Field teams at avalanche centers document the snowpack—the thickness and type of snow layers—and combine those data with weather conditions to estimate danger levels. The forecasts take into account the potential type and size of an avalanche, the likelihood it will occur, and the location. Before entering the backcountry, check online forecasts for the danger level in that area. Each mountain range has unique snow properties and therefore, avalanche risks, so checking your specific region is critical. New Zealand , Canada , and Europe also maintain year-round forecasts of avalanche danger for specific peaks and wilderness areas.
Experts recommend hiking and travelling earlier in the day. Weather conditions can change rapidly, and warming during the day creates more unstable snowpack with a higher risk for avalanches. Education and proper training on avalanches can help prepare you.

Heed all warnings and signs. Some accidents have been traced to people avoiding warnings due to psychological traps , like desiring the ultimate ski slope, untouched by humans. Constant vigilance when you are outside can help avoid causing or getting swept up in avalanches, but even trained experts can be become victims. Be aware of the weather and terrain, and know your comfort level before you embark on an adventure.
Read more about avalanche safety tips. If caught in an avalanche , try to get off the slab. In best case scenarios, this is difficult.
Landslides and Mudslides|CDC
Skiers and snowboarders can head at a degree angle downhill to gather speed and veer left or right out of the slide path. Snowmobilers can punch the throttle to power out of harm's way. No escape? Reach for a tree. No tree? Swim hard.
The human body is denser than avalanche debris and will sink quickly. As the slide slows, clear air space to breathe.
Then punch a hand skyward. Once the avalanche stops, it settles like concrete, making body movement nearly impossible.
