Danger Scale

We toured near Saddle Peak in the Bridger Range and found a wet, weak snowpack on sunny ☀️ slopes and lower elevation slopes.  Northerly facing slopes above 8,000’ had dry stable ⛷ conditions. 
The snow surface has been freezing overnight and is generally stable in the morning when it has a supportable crust. Anticipate decreasing stability as this crust melts and is less supportable. #gnfacobs #saddlepeak #wetsnow

Yesterday, a snowbiker was partially buried in a slide on the west side of Sage Peak in the southern Madison Range. The slide occurred on a southwest facing slope at 8,700 ft. and failed on weak snow near the ground. The wet slab avalanche was triggered as the biker was side-hilling across the slope. He was caught, carried and buried to his chest, but fortunately escaped unharmed. The snowpack on south and west facing slopes is turning isothermal and losing strength rapidly. Avoiding steep sun exposed slopes is recommended until temps cool off.
