The new windblown snow was way more sensitive today than I expected. A density change just above the old snow surface got buried by slightly more dense snow creating a bit of an uspside-down storm slab. After triggering a couple small pockets on the Flagstaff uptrack we attempted to look into Two Dogs. The cornices have grown to Adult size and we couldn't safely get close enough to see over the edge. As I traversed along the ridge to exit a portion of the cornice broke about 30' away from me and triggered a SS-ASr-R2-D2-I that propagated across most of the slope. It moved with speed but was quickly slowed as the slope angle lessened. Most of the slides today were small and didn't pack much punch but this one was large enough to ruin your day. Only one pic due to poor vis.
