Spring cycle in White Pass

Widespread spring avalanche cycle with lots of wet loose release since weekend in white pass west and east sides of highway. See avalanche report. Still a lot of snow in the mountains and good skiing considering it is the end of May. HS average 150cm at Bryant Lake (1075m). Lake is starting to melt, open water at edges and outflow. We ground-truthed HS at YAAFRA is 75cm. Wx: No overnight refreeze at Fraser even tho frost in Whitehorse, temp 5C at valley bottom at 10am, 10C at 3pm and snow was isothermal at trailhead mid-afternoon. Sunny day, mod south wind and cloud rolled in late aft. Bears are out!

Widespread avalanche cycle with wet loose slides on all aspects in last couple days in White Pass (guessing since May 25th). Today we observed hundreds of paths with fresh debris in alpine from Tutshi thru to Fraser. Point releases from alpine rocky features, off ridge lines and some triggered by cornice breaks. Most paths appear to be shedding the top 30cm or less, over past couple days-suspect warm temps or set off recent storm snow running on a crust. Not much entrainment, but sheer number of avalanches was impressive (average sz 2) mostly narrow long tracks typical of spring loose wet point releases. A few lower elevation tracks to ground with dirty debris on south aspects. Above Bryant Lake all aspects have recent wet loose activity widespread spring cycle. Notable was North facing path in Big Kahuna feature - one of few that stepped down and involved some slab, and ran full path to Bryant Lake.
