Quick report

Cracking
isolated
Collapsing
isolated

We observed touchy and easily triggered wind slabs that stepped down to deeper buried weak layers at mid and upper elevations while touring today. We also found good powder skiing in wind-sheltered lower angle slopes and variable surface conditions throughout (classic spring). Observed localized collapses from 4800' on up on N, NW, and NE aspects and localized cracking (up to 2m) in wind loaded terrain features. No recent avalanches observed until we both intentionally and unintentionally triggered avalanches (described in avalanche section).

We triggered two wind slab avalanches and one persistent slab avalanche that were easy to trigger, propagated short distances, and stepped down into recently buried near surface facets.
