Avalanche: Hatcher Pass
Location: Base of Granite Peak
We headed up the groomer toward Granite Mountain. We arrived at the base just in time to witness one wet slide and notice
new debris from others before turning around and water skiing back to the car.
Avalanche Details
Rapid warming lead to plenty of shedding of unconsolidated snow on east aspects (and likely others) We witnessed the slide on the right run slowly but powerfully over an existing debris pile. It appeared that a small point release on a northeast aspect triggered a lowish angle D2 wet loose avalanche. We turned around and skied the slop back to the sticky groomer.
