Very warm temps on the afternoon of 4/1 likely contributed to this wet slide cycle on the lower reaches of Miller Hill Southwest. Point releases entrained quite a bit of snow and ran down to the lower angle slopes just above the MEG road in the bottom of the drainage. There was also evidence of wet loose slides on South Facing MEG underneath the large rock bands. Debris piles were sizable and could have easily buried a person. Picture 1 is of Slides on Southwest facing Miller Hill. Picture 2 is shows debris pile on South Facing MEG in lower right portion of the frame.

Lots of snowmobile tracks on all aspects of MEG, but it did not seem that they were the cause of any avalanches.
