Avalanche: Chugach State Park

Location: Hanging Valley

Route & General Observations

Skied from Harp Mountain parking lot out and around to Hanging Valley. Bluebird sunny day, 0 degrees at the car but warmed quickly in the sunlight. Skied a southern aspect then skinned deeper into the valley ascending small hanging bowl with a lake. Ascended eastern aspect to 3800 feet before turning due to red flags. Avalanche occurred on eastern slope upon exit. Large shooting cracks, basal facets, and roller balls were observed on the eastern sunbaked slope. Observed numerous natural slides later in the day. One avalanche came off the shoulder of Harp mountain that buried the skin track and strained through the trees (later to be found out it was triggered remotely by a snowboarder).
