Observation: Chugach State Park

Location: Glen Alps - Blueberry Knoll, Chugach Front Range

Route & General Observations

Left Glen Alps PL at at 1330 and toured up the NW aspect of Blueberry Knoll to the ridgetop. Did not observe any signs of recent avalanches in the Powerline Proper or on Flattop other than the small human-triggered slide on Boy Scout (Snowboarder) Hill that occurred during high winds and new snow transport on 1/29/23. See observation by anonymous for that day titled “Boy Scout Bowl” describing that event. People were skiing the steepest sections of that hill today apparently without incident.

Snow surface

In meadows area found a 90cm snowpack in protected areas. Approximately 5cm combo of new and wind transported snow at surface resulting from storm event of 1/29/23. underlain by interlayered rounds and facets. In some small protected areas observed a saran wrap-thin ice glaze "firnspiegel" on the snow surface. As usual the ridgetop was stripped of any new snow by high winds that came with the storm event on 1/29 (pic).
