A windy and warm morning with moderate-gusting-strong Southerly winds. These winds remained through the day as forecasted and managed to transport nearly all of the transportable snow, despite its high density. Sastrugi covers south aspects and areas that saw drainage-influence wind.
Saw a number of small (D1) avalanches today off of the East and West Bowl headwalls in Silver Fork, I'm guessing natural cornice-triggers occurring during the high-gusting wind overnight (Potential for a few to be human-triggered from ridge-walking yesterday). These pieces were all in steep, rocky terrain, lee side of the LCC/BCC ridge, ~8-14" crowns generally with debris <2 ft. depth.
Photo 1- East Bowl 10,200'- Crown visible upper right, shallow debris ran a few hundred feet.
Photo 2- West Bowl 9,900'- Crown visible upper right, one of a number of similar pieces along the West Bowl headwall.
All debris shallow, failure was likely the overloaded interface created when 11/2 snow fell.
Photo 3- Wind transport was consistent today throughout drainages, accented along ridges. Ridge travel was a treat...
