It is unlikely to trigger an avalanche on buried weak layers 1 to 3 feet deep. Surface crusts reduce the likelihood that your weight will collapse the weak layer. The upper snowpack has become weak and faceted, altering the properties of the slab.
You can reduce your group's exposure by riding steep slopes one at a time. Position partners in safe locations while the other rides or descends steep terrain.

This large, natural slab avalanche in Skyland (Slippery Bill Mtn - NE - 7300' - D3). This failed sometime in early-mid January.
