Comments
I passed by this avalanche on my second lap along the Emma South faces at approximately 10:00 am. It is located between Two Dogs and Oingo Boingo in steep, potentially wind loaded, North facing terrain. Looked to have occurred after the storm had ended. Not sure if it was remotely triggered by one of the many parties traversing the Emma ridgeline above or if it had happened right at the tail end of the storm. Appeared to have immediately stepped down to the ground.
