Avalanche: Juneau Mainland

Location: Juneau Ridge, and Gastineau and Roberts Peak

Route & General Observations

Toured up to the Juneau ridge yesterday and noted several wind slab avalanches on steep north facing terrain near ridgetops – most notably off the Juneau ridge, Gastineau Peak and Mt Roberts. All of the crowns observed were below well developed cornices, which we are assuming served as the trigger. Based on weather history, we believe these avalanches occured during the higher winds on March 8th. We did not observe any deep slab avalanches.
