Northern San Juan

You can trigger avalanches on steep slopes at all elevations. The most dangerous slopes are at upper elevations where dense, cohesive slabs of snow formed over widespread weak layers. Avalanches here could break deeper and wider than expected and be large enough to bury you. Avoid traveling near common trigger points, such as convex rollovers, thinly spaced trees, and rocky outcrops where you may find a shallower spot in the slab. 

Cracking and collapsing are signs of an unstable slope and an indication to move to lower-angle terrain. You may not observe these signs of instability before triggering an avalanche. New snow and wind on Saturday will keep avalanche danger elevated through the weekend.
