West Central Montana Avalanche Center

Still a relatively shallow snowpack, the recent warm temps seem to have helped the upper layers, but basal facets are still present, and more concerning, they actually propagated in an ECT in this pit, albeit with a good bit of force and a very poor quality shear. Overall things seem to be improving, but still a very questionable, very weak incohesive layer right above ground in our snowpack.

Pit was dug in within the boundary of a ski area, however location is a closed area with no skier traffic and no control work done at this point in the season, so should be fairly representative of similar slopes in the backcountry. No propagation during standard ECT test, but did get propagation at 93cm at 11 upon hitting other side of column after test completion. Overall looks better than the more northerly slopes in area, no depth hoar formation noticed, however still some significant faceted layers, in particular from 21cm to ground that have very limited cohesion.

Lots of roller balls and loose wet sluff on all aspects due to the warm temps. Buried surface hoar layer at 120cm still has cause for concern. Grains seemed to be starting to heal, but still a little reactive in tests. Did not propagate more then a few CM's on ECTN25, but propagated the rest of the way across and came out high energy with some hits on the other side of the column after test completion.
