Quite the size 2+ avalanche cycle yesterday in the upper Cottonwoods. Seems to have rapidly settled out for today. Snow profiles on many aspects at the mid and upper elevations similar in structure: photo below. Roughly 30-50cm of settled storm snow above the old melt freeze crusts. ECTN and CT in the upper 20s. Only stepping above an old crown near Twin Lakes could I get a crack to propagate even 5' ahead of my skis.

Rapid warming producing "creep" within the upper portions of the storm snow. Note how much the slab has crept over the old fracture line. Fracture lines are perpendicular upon release and this crown is perhaps 24-28 hours old. I wrote a paper on an avalanche cycle from March 2012 stemming from solar radiation and heating...though those were very different conditions.

Photo of minor push-a-lanche into northeast facing terrain above twin lakes. Much dependent on even a brief window of sun to enhance the already warm and greenhousing temps.

Obligatory calendar shot of the cornices lining Wolverine.
