Observation: Chugach State Park

Location: Glen Alps Recreation Area

Route & General Observations

We went down Powerline Trail and up to the bench in between False Peak and the Wedge to gauge overall snow depth coverage and to monitor the Thanksgiving crust layer.

Snow surface

In most locations, the snow surface was wind-affected. Sastrugi, ripples, and wind deposition pockets were observed. When we were up at the base of the Wedge and the base of Avalanche Peak it was white-out conditions. We could not see more than a couple of feet in front of us. There were large patches of bare ground- especially on the bench between the Wedge and False Peak.


We did observe the Thanksgiving crust and a thin layer of facets at the base of the snowpack. Neither of these layers demonstrated propagation or showed any reactivity in our snow pit. However, we are still monitoring these layers and will continue to monitor them throughout the season.

Good stability, poor structure, and low propagation propensityWe dug one snowpit.
