Clear wind loading and reactive cornices, however storm snow was low energy with little movement. 10-14 inches of medium density snow.

Was splitboarding up near lions head ridge today. Made some bad decisions and kicked off a good slide in a NE facing chute. Was with 2 buddies, 1 of which skied the line 3 weeks ago. Underneath about a foot of new powder snow there was a firm crust that seemed like it was old hard windslab in the gut of the chute, and I think a sun crust on the riders left side(East aspect). We had 2 spots where we were planning to re group at, first was a small cubby area right before a slight rollover about 75 ft from the top. I dropped first, made some turns down toward the pulloff, as I pulled in, I triggered a good size slab that propagated maybe 40-50 ft across, at the rollover as I carved into the pulloff. Pulled all snow out of the chute down to the ground. Seemed to have failed on sugary facets on ground/ice crust close to the ground...
