Once you get into higher alpine terrain near the Cascade Crest, you will start running into recently fallen snow that has been previously drifted. Look for clear signs that unstable slabs exist, such as shooting cracks from your equipment or recent slab avalanches. Wind slabs typically form just below ridgelines and within concave terrain features (cross-loading). You can use tactile and visual clues such as textured, uneven snow surfaces and a change to denser feeling snow underneath you to help guide where slabs may lurk. The likelihood of triggering a wind slab is trending down, and it's unlikely you'd trigger one big enough to bury you. But a slab could sweep you off your feet and carry you into terrain traps below, so be conscientious of the terrain you're choosing before diving into something steep.

A longer shooting crack in wind-loaded snow indicates instability.
