Weather and Snow
Current Conditions: Riding conditions were deep on Wednesday. Trench warfare on sleds. Step off your machine or skis and you sink right to the ground. Total depths in the higher terrain are right around 3 feet. The new snow is fairly dense so you can actually travel around. Overnight temperatures were in the low to mid teens and the wind from the northwest was fairly light.
Mountain Weather: We move into a prolonged period of mild weather starting today. We'll see mostly clear skies with high temperatures in the low 20s and light to moderate speed west northwest wind. The forecast looks the same for the foreseeable future although with a gradual warming trend.
Recent Avalanches
There was lots of "pockety" avalanche activity during the tail end of the storm as well as a few small snowmobile triggered slides on Wednesday. The avalanches were breaking about 2 1/2 feet deep. They ranged from 100 to 200 feet wide. None of them ran all that far because they were all on fairly small slopes. Photo below is an example of what type of avalanches occurred.

Description
All the signs are there. Recent avalanches. Collapsing. Poor snowpack structure with weak sugary snow at the base. Poor stability test results. What more do you need? It should be obvious from all these clues that we have an unstable snowpack. You're going to want to avoid the steep slopes through the rest of the week and weekend.
