Pass Zone: No turns but a sunny drive over the pass revealed numerous natural, wind slab avalanches, particularly between the Jarvis Glacier and Rainy Hollow. Avalanches were observed in terrain loaded and cross loaded by NWerly winds, primarily cross loaded gullies above 3500'. Crowns appeared to be 25-50cm deep, most slides size 2 within specific terrain features, running 100-200m and small relative to path. I estimate most of the avalanches observed ran in the last 72 hours given the appearance of the crowns and the ongoing snow transport at all elevations, possibly reloading paths. The bed surface is the interface between the old snow surface and the newly formed wind slab. Originally posted by Jonny Bomber on Haines Avalanche Snow Page
