More detailed information about the avalanche: 

This is old-ish activity that I am guessing occured during last week's storm (2/3 to 2/10). 275 is Calf Robe Mtn, 276 is between Elk Mtn and Little Dog Mtn,  283 shows how wet it was, 295 Northeast aspect of Elk. All pics are from the Autumn Creek west trail except for the pic of Calf Robe.

Just wanted to share.
