Avalanche: Chugach State Park
Location: Glen Alps, Chugach Front Range
Left GA parking lot at 12:30. Skied SE through the mdws area along the base of the NE aspect of Blueberry Knoll. Did quick pit there. Climbed up to and skied W. through the wind tunnel and onto the W aspect of Flattop. Watched people sliding down the Wind Tunnel avalanche path (pic). Did pit here then headed NW along the Blueberry Knoll ridgetop and back to GA PL at 5 pm. Observed evidence of recent point release avalanches on the S. aspect of the ridge between Rusty Pt. and Wolverine Pk. Pics attached.
Avalanche Details
Observed debris from three point release avalanches in steep gullies on the S. aspect of the ridge running between Rusty Pt. and Wolverine Pk. One ran on snow bed surface whereas others broke to the ground. At least two probably occurred during the afternoon of 3/11. Pics attached.
Observer Comments
Recent point-release avalanches on S. aspect of ridge running between Rusty Point and Wolverine Pk.
Weather
A pleasant bluebird day with calm winds. At 3:30 was 23deg.
Snow surface
The usual Glen Alps area spatial variability. In the mdws area N. aspects had MF crust overlying faceting wind-broken grains, overlying several layers of rounding facts. Indications of recent wind transport (pic) Ridgetops wind blasted to concrete made it hard to hold an edge on skis (pic). Sun crust forming locally on SW aspects (pic).
Snowpack
Did Quick pit at 2000ft on 15deg NE aspect slope in the mdws area. HS = 75cm. Got CT22@20cm down. Facets over MF crust. Did a complete pit (attached) on the SW aspect of Flattop Mtn at 2520ft. Local sun crust overlying near-surface facets (pic). HS = 77cm. Got CT23@17cm down and ECTN21 on same weak layer consisting of facets overlying a MF crust.
