For Thompson Pass area- seems the winds shifted slightly in direction to more NE rather than ENE which has been the trend the last few days. The wind shift in addition to winds peaking in gusts through out this bluebird cycle (at least on Thompson Pass summit) to 50-60mph, created a bunch of new fresh, sensitive wind slabs. The older windslabs created were not reactive.

Avalanche

Smaller D1 windslab naturally triggered, consisting of fresh wind redistributed snow up near the entrance of the basin of the Iguana Backs. Also triggered a D2 windslab on the Iguana Back buttress, 6''-2' deep, 150' across and ran about 2-300 feet, on a steep convex roll over, in the lower elevations near in the alder.
