Avalanche: Chugach State Park

Location: Harp Mountain

Route & General Observations

Skinned up Harp ridge. localized whumping of top layer of unconsolidated, wet slush. Observed 5 D1 wet loose slides, all skier triggered. Skier triggered slide on N/NW aspect, buried up to waist, able to self-resuce.

Additions from skier involved:
I was with a partner. No injures. It was difficult to get out due to the weight of the spring snow. We did not continue…exited Harp as safely as we could. The other D1s in Harp bowl were N, NW, S/SW, S/SE. It seems like all aspects were extremely reactive. They were all similar elevations (3000-3500) and slope angles (35ish-38ish). The largest slide was on the S/SE aspect, skier triggered and he was able to ski out. I should’ve taken photos of all of them, sorry. The observation photo was on the N/NW aspect of the bowl we triggered. It stepped all the way down to the ground, we suspected it could have been the january facet layer or basal facets. We need a re-freeze! Very saturated pack right now.
