Beware of any slopes where you come across more than six inches of drifted snow. The strong winds can create unusual loading patterns, and slabs can form further down the slope than expected. Avoid textured snow resembling a pillow and steep terrain where the new snow cracks. One of these avalanches could break into a more deeply buried weak layer. Look for wind-sheltered slopes without a cohesive slab or slopes less than about 30 degrees for safer travel options.
