Red Flags
Wind Loading, Cracking, Collapsing, Poor Snowpack Structure

Travel today was up Thomas Fork in Neff's Canyon. We observed multiple shooting cracks and were able to pull out a few small pockety windslabs. Even the snow in lower Thomas Fork (below 7k feet) was touchy and surprisingly reactive.

Instability Comment
<p>Even outside of wind-affected areas, the new heavy snow was failing and propagating on the new snow/old snow interface. We saw a ton of shooting cracks and experienced a number of sudden collapses while skinning up, even at low elevations. There wasn't enough new snow at the time of our ascent to be seriously concerning, but with additional loading, this could be a serious problem. Very touchy conditions.</p> <p>Higher up in Thomas Fork (between 8200 and 9600 feet), we encountered pockets of wind drifted snow on North thru West aspects. The wind slabs were more cohesive and less touchy than the heavy storm snow down low, but we still saw multiple shooting cracks and collapses while skinning. While skiing down I was able to pull out a small, wind-drifted pocket under a rollover. </p>
