Observation: Chugach State Park

Location: South Fork of Eagle River

Route & General Observations

Standard up track to North Bowl to look at weak layers. We found some concerning snowpit test results on the faceted layer at the base of the snowpack.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

10:00 am- valley fog, no wind, no precip
11:35 am- above valley fog, broken skies, no wind, no precip
12:30 pm- valley fog dissipates, broken skies, light wind

Snow surface

The snow surface was wind-affected by both scoured and wind-loaded areas. We did find a rain crust at lower elevations that dissipated around 3,500'. Above 3,500' we found a thin layer of rimed precip particles.


Snow depths ranged greatly on our tour. We observed bare ground to over 4 feet in wind-deposited locations.

Snowpit Info:
Height of snowpack: 120cm
Location: South Fork of Eagle River
Elevation: 3,900'
Aspect: NW
Slope: 29 degrees
Test Results: We observed propagation (showing poor stability) on the facets at the base of the snow pack (ECTP12). This is concerning to us as it shows the snowpack could produce a large avalanche.
