Avalanche Date: 
Friday, March 3, 2017
Location Name or Route: 
Upper Ephraim Canyon

Snowmobilers triggered several avalanches on steep leeward wind loaded slopes.  Judging by the photo, it appears that the slope was facing the sun enough for it to heat up and possibly make the drifts become unstable.  Theser are the type of human triggered avalanches that are still possible along the highest ridgelines.  This is why the avalanche danger is still rated at MODERATE for these areas.
