Observation: Chugach State Park

Location: Baldy N. Side

Route & General Observations

Toured up backside Baldy. Lots of active wind-loading and transporting snow. Sensitive, but thin (5-30cm), fresh wind-slabs resting on slick tundra, or older, slick windboard or ice. D1 avvy observed north aspect ~20m from the ridgeline with ~100 m runout. Big blocks up to 2m within this slide would give anyone a bad day or possibly kill a dog. It occurred Fri night. There are a couple nearby gillies that could focus/funnel avvy debris from other windslabs and potentially bury a person. If you ski here I’d recommend taking the summer trail away from steep slopes and gullies (terrain traps) as a skin track. I see folks cutting across the base of the steepest slope annd/or skinning up gullies and it makes me nervous. Also, with a skin track in a safer location we don’t have to ski across skin tracks on our powder run. This is only the 3rd avalanche I’ve seen in this zone in ~10 yrs but be aware. Safety and powder preservation 👍
