Weak layers of snow are distributed across all aspects and elevations. Although the sensitivity of these layers has decreased since the January 26th storm, stability tests are still proving these layers could trigger an avalanche.Slab depths range from 1-3 feet. Areas with a shallow snowpack and firm, cohesive slab above these weak layers on steep slopes over 35° have the highest likelihood. Dig down to identify these layers and perform stability tests before committing to steep slopes.
