Observation: Chugach State Park

Location: Mt Magnificent / Eagle River

Route & General Observations

Natural avalanche on SW face of Mt Magnificent following 1/8 N winds (sometime between 1400 1/8 and 1200 1/9). Estimate starting elevation around 3800′, ran to maybe 3300′. Some hoar-namented powder on N aspects below 3k’ escaped the maelstrom. Until… After a calm 1/9, winds kicked up stronger on 1/10 and converted the remainder to sastrugi and exposed tundra.
A few smaller naturals were also visible on similar aspects near ridgetops along N side of Eagle River valley.
