Snowpit Observations
More detailed information about the snowpack: 

Below treeline, evidence of skier triggered sluffing of top 4 inches from the day before was widespread in open areas steeper than 37 degrees. Today there was no evidence of instability below 8,500'. From 8,500' on up minimal cracking up to 2 feet long occurred while trail breaking in lightly wind effected areas below treeline. At treeline a pronounced surface slab existed in wind loaded areas on NE-E aspects. Snowpit data just above treeline along the summit ridge produced inconsistent results on a buried wind slab. Likely difficult to trigger until the exact right trigger point was found. Minimal skier triggered sluffing of the top 2 inches of new snow in below treeline areas on the descent in terrain steeper than 37 degrees.
