Quick Observation
Quick outing for some beacon training on the Stillwater State Forest:
2 recent D2 avalanches on SW aspect. Guessing these ran 3/13-3/14.
Northeast aspect at 5000' had 1/2" crust breaking down by 1pm. This was semi-supportable on foot as every couple few steps we would posthole thigh deep.
Noticed old roller ball activity on NW aspect upper elevation. Probably occured during 3/14 greenhousing.
Road is losing snow fast. Lots of patches of glare ice and some big ol puddles.
