Woody Ridge obs

Date
Activity
Skiing

While on a tour today out in Republic Creek, we decided to skin a forested W aspect to gain woody ridge. As we started to near the alpine, we dug a pit on a N aspect at 9900ft and in return got a ectp24 at 30cm in our test. Snowpack in the area was roughly 110cm. The snowpack failed on a buried crust layer that has not bonded to the new snowfall.

Future concerns for beehive

Activity
Skiing

ECTX on our snow pit on a shaded, west-facing aspect but sun has created a thin crust as well as some pretty large facets on the surface. Looked like wind had collapsed most of them but could cause problems after next storm
