What and where is it: You could find small slabs of wind drifted snow in wind-protected areas of steep, east-facing terrain above 3000 feet in elevation. Where slabs exist, they are generally small and limited in size, most commonly found at mid elevations in sheltered gullies, below rollovers, and behind terrain features that collect drifting snow. The Summer Lion Head Trail and the Gulf of Slides are examples of where these drifts have been seen.How can you recognize it: Watch for areas of snow with a smooth, rounded, or pillowy surface where your feet penetrate deeper than the tops of your boots. Dig into the snow and use shear or compression tests to better understand the sensitivity of any small wind slabs.How can you manage it: If you find a slab deeper than boot-top, stop and assess how big it is, how continuous it is, and what’s below it, as it may be more consequential. Travel on firm, wind-hardened surfaces if you find a concerning area of deeper, softer wind slab.
