Comment
Weekend of March 31 - April 2
Climbed Baden Powell three days in a row to enjoy latest snowfall and observe the transition into our first days of spring like weather. 

Other than wet loose concern we observed large hanging cornices over leeward ridges on northern slopes above 9000’. Most are exceptionally large given our usual snowpack and are hanging and convex. Average cornice sizes are anywhere between 10-20’. There is already evidence of some failing due to the rapidly warming temperatures. Wet loose slides riddle BP’s drainages and are evident on all aspects, although none no larger than d1/r1, but that can change as the weather warms into April and May. 

Snow depths are still beyond measurement via my 280cm probe above 8500’
