Avalanche: Chugach State Park

Location: The Nipple

Route & General Observations

Springtime skiing in the South Fork Eagle River area. Started from trailhead, and ascended via Hunter Pass, ridge line, to “The Nipple”.

We were on the peak around 2:30pm, and nearby Arctic Valley’s station was reading 21F. The snow in the gully skied surprisingly well, a wet kind of powder as we were descending. I suspect the wind had loaded the gully with this weeks fresh snow, on top of a harder frozen layer that acted as the bed surface.

Avalanche Details

Snowboarder 1 started from The Nipple, riding along the ridge line and off a cornice which had been checked for instability on approach. Snowboarder 1 then entered the bowl and rode approximately 1000ft down slope and waited in a safe zone to spot Skier 1. Skier 1 followed a similar line, slightly higher, but at approximately 3400ft elevation triggered a medium sized soft wet slab avalanche. Snowboarder 1 called avalanche as Skier 1 turned hard skier’s right, to the safety of exposed ground on the spur. Partners consolidated in the safe zone at bottom of run and skied to South Fork Hiland Road trailhead.
