More detailed information about the avalanche: 

Turned turned around at 12800', 1130 due to strong warming and rollerball activity as well as a few D1 Loose wet slides on a similar aspect and elevation which originated near rock outcropping in steep terrain.

A single skier came down the upper East face route and triggered a small loose wet slide which then entrained the rest of the 25cm of new snow and slid on the old snow interface (P hard) and ran 1600' x 100' wide, D2.
