Today was one of those days that we decided to stick inbounds as visibility was poor and stability in the backcountry was not something we decided to tempt.  I was fortunate to tag along with Jordan to look at Crown on Highline Ridge in Tresckow in the early afternoon after an explosive mission in the morning.  This slide was the result of a two pound explosive in the snow.   This area had seen no previous explosive use and had not run prior to today, which is why I thought this would be relevant to what are seeing in the backcountry.  Typically inbounds avalanches aren't representative of what we see in the backcountry, but early season conditions before skier compaction we are typically dealing with a similar snowpack, which is why this result is so relevant to backcountry conditions.  Wx Station and manual snow water equivalnent data has registered over 2.5" in this storm, which is a tremendous amount of weight on the snowpack for this area.  Winds picked up last night into about the 8AM hour with sustained winds in the 20's out of the West.
