Snowpack
Another party dug a pit next to skin track (Far skier's right side of the bowl) and reported 3 ft of snow, ECTP 17 Q1. We intended on skiing the NE, ENE aspect so once at the top of the bowl, we traveled down the ridge to dig a pit. Found 6-8 inches of snow near ridge top, composed of 3-4 in of facets with 3-4 in of new snow on top. About 50' downslope the snow depths increased to about 2 feet.

On the second lap, decided to ski further left of the trees, closer to the center of Marble Bowl. Slide went on 2nd skier, who skied close to skier 1 tracks. Aspect ENE, elevation ~11200. Skier 2 skied about 75 ft. down and over convexity before triggering avalanche. It propagated uphill and to the left ~150 ft. skier cut right with direction from other member of the party. The slide ran ~750 ft. Group consensus was R2D2 in size. Crown was 12-18 inches
