Tutshi-Wheaton-White Pass East-White Pass West — Bollettino valanghe

No new avalanche activity has been reported since Wednesday, when numerous loose wet or wet slab avalanches were reported on sun-exposed slopes near White Pass.Last weekend, a wind slab avalanche was remotely triggered and surprisingly large due to surface hoar buried just below the recently formed wind slabs.

A variety of surfaces exist across aspects and elevations. Firm, supportive crusts are present at lower elevations and on sun-exposed slopes.In higher-elevation terrain sheltered from sun and wind, 10 to 15 cm of recent snow overlies a mix of older, wind-affected surfaces.A weak layer of surface hoar may persist 30 to 60 cm below the surface in northerly alpine terrain.The lower snowpack remains faceted and generally weak, especially in shallow snowpack areas.
