This month’s snowpack update comes as we transition from winter to spring. As of March 22, the Snow Water Equivalent (SWE) totals in west central Montana are just above average (Figure 1). After a month of small storms and average temperatures, our primary avalanche concerns are focused on...
Snowpack Discussion The snowpack continues to evolve in West Central Montana. In late January, our primary avalanche concern was persistent slab avalanches failing on facets at the bottom of the snowpack. During this time period, several natural persistent slab avalanches failed near the ground. Although the exact timing remains...
Avalanche conditions from January 11th until January 24th have been at considerable danger, trending towards moderate danger. We are currently most concerned with persistent weak layers, failing near the ground on depth hoar and facets. The second problematic persistent weak layer is a combination buried surface hoar, near-surface facets, and crusts. This weak layer is found at different...

Generating backcountry travel plans without avalanche center forecast information requires knowledge of weather events. Review snotel data for current snow totals and weather station data for temperatures, wind trends, and speeds. With these tools, you can get an idea of the avalanche problems you could encounter on your trip and choose appropriate terrain...
