Cold and cloudy today with poor visibility near and above treeline. Very light snow showers at times with light winds up high.
We observed a recent avalanche on a north aspect of Hinkhouse Peak which likely ran on Monday 2/20. The debris was a 2 on the D scale; large enough to bury injure or kill a person. The debris included cornice chunks and was covered with the same new snow that has fallen since Monday.
Snowmobile travel on highway 20 is not wonderful with a crusty refreeze and lots of whoops. This refreeze is from Monday and Tuesday's warm up. At 4000' the crust starts to get a dusting of new snow. As we skinned up north aspects of Hinkhouse, the new snow from Monday and Tuesday got deeper. This new snow is variable in depth from 0" to 20" in places. It shows signs of wind effect near and above treeline. In spite of the obvious wind effect, we didn't observe any shooting cracks or other signs of a reactive wind slab, at least up to 6800'. So long as we found corridors of wind deposited snow, we enjoyed low density boot deep powder skiing. There are some considerable frozen chunks under this new snow. We dug a pit on a North aspect at 6400'. The new snow didn't show us signs of reactivity. We performed an extended column test and got no results (ECTX). We also didn't see anything in a compression test (CTN), but we did get a sudden planar result in a deep tap test 1 meter down. (DTM SP @ 100cm). We think this layer is the old Jan. 5th surface hoar. We don't think this a problematic layer right now, but it's worth keeping track of.
Layer Depth/Date: 20-30"
Comments: Conrinces could be reacive in places
