Avalanche: Chugach State Park

Location: Harp Mountain

Route & General Observations

Skied the bowl to the North of Harp today. 6 people in 3 separate parties on the same skin track up the ridge to the immediate north of Harp proper. Chose this route bc less hazard than skinning up the valley floor until we could get a look at the avy conditions. Lower down there’s 5” dry powder on mostly supportable crust, tapering to 2” by 4000’. Difficult skinning at times due to icy crust under powder. Observed 2 avalanches of uncertain age (but appear recent) on similar NW aspects on 2 ridges. (see pics). First party dropped south (towards Harp proper) into bowl at approx 4000 feet. Our party booted to ridgeline, then south down the ridge line a bit, then skied into the center of the bowl from 4500 feet. Didn’t see 3rd party drop in. No shooting cracks or whumphs. Hand pits along skin track revealed stout icy crust 2-5 “ under loose dry pow. Lotsa facets and sometimes additional crusts lower in snowpack.
