AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Persistent Slab

Layer/Depth:
70-105cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:

Terrain
  Primary Concern Comments: No test done on problem at low elevations.
 Comments: Did not get into any terrain where wind slabs would be a problem.
STABILITY TESTS
 Stability Test Results: PST 90/100 END on ESE @ 8700'. Some ECTN's on interfaces in recent storm snow. ECTP25-30 down 105cm on FC. Propagating ECT results are in an area that I've seen harbor the weakest snowpack near Baker Lake all season. I have found that spot to generally have poorer stability than all other areas i've dug.

BOTTOM LINE
 Comments: A few cm's of glop at Baker Lot. Seems like early AM rain made it to around ~7200' in this area based on soft crusts and new snow. Shaded low elevations moist to around 20cm in depth and then dry FC below that. Didn't travel through upper elevation terrain but can imagine some thin wind slabs forming. Did not observe any recent wet loose activity in the area from the past few days.
