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.
