Heres a profile from a very nearby location on the 12/14 with a similar aspect, but slightly lower elevation than this avalanche. I believe these avalanches ran on the basal facets from 39cm and below, but that hasn't been verified yet.
A number of pictures below showing the documented avalanches we had during high precip rates last night.

Ipana bowl ran D2 as well.
Gunsight notch ran.
Snowslide Junior also ran, and almost made it down to the bike path.
