Observation: Girdwood

Location: Crow Creek

Route & General Observations

We went for a low-angle sightseeing tour up Crow Creek to take a look at conditions and enjoy the sun. We toured up to 4900′ and dug a pit on a northwest slope at just under 3000′. We found a similar snowpack to what we’ve been looking at around the advisory area, with a shallower (2′ deep) slab sitting on top of the 3/14 facet layer. We’re still operating with very little info from this area.

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

Sunny skies with mild temps and light northerly winds that added a chill. Winds were strong enough to blow quite a bit of snow around up at ridgelines.

Snow surface

We traveled across a variety of snow surfaces, with a trace to 3" low-density snow on top. Most slopes had a supportable crust just under the newest snow from wednesday night, but some of the high shaded slopes were spared from the crust. Steep solar aspects were getting warm enough by about 2:30 p.m. to start seeing rollerballs and rocks falling down steep slopes. We saw one long-running loose snow avalanche on a SW aspect that happened around 4:00 p.m.


The snowpack in this area showed a lot of similarity to the rest of the advisory area. Specifically, there is a hard slab sitting on top of a layer of facets. The two big differences were (1) the slab is about half as deep in Crow Creek as it is in the pass, and (2) the weak layer doesn't seem to be quite as weak. It is really important to note that we only dug one pit, so I am really hesitant to draw any broad conclusions. It is quite possible that we could have dug just around the corner and found a different setup.
