Observer Comments

No obvious signs observed. We bought binoculars and scanned the nearby peaks for snow pack information. Didn’t see any obvious signs of recent avalanche activity. Rocks up high on Ptarmigan peak looked glazed over with ice but didn’t see this at lower elevations. Looked like a lot of snow had melted off (see photos).

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

Warm! Was 37 degrees F at the cars in the morning. Mostly calm all day with good visibility.

Snow surface

Rain crust, 1/8 to 1/4 inch thick, at the surface over much of the area (see photo). A lot of variability in ski and boot penetration mostly due to past wind effect. Around trees, ski penetration was 2-3 inches and much deeper for boot penetration. Out in the open, surfaces were very hard and easy to walk on.


Shallow snowpack in the area where we were for the day. In open areas away from trees, snow depth was 30 to 50 cm (based on probe poles).
