Avalanche Summary
You can trigger a small avalanche on steep southerly slopes where around ten inches of drifted snow rests on a firm crust below. Avalanche in the new snow could step down, triggering a larger avalanche in cross-loaded and east-facing terrain. It has been over a week since the last report of a large avalanche breaking on weak snow near the ground, but it remains the primary concern as it would lead to a more dangerous slide.
Avoid slopes steeper than around 35 degrees with a smooth, pillowy appearance or areas that feel hard and sound hollow. If you see shooting cracks, hear collapses, or transition from soft to harder snow, choose an alternative route or different slope. Lower elevation slopes without steep overhead hazards offer safer travel options.
