Snow surface

Light, low-density fresh snow over 12" deep for the majority of our tour.

The snow depth still varied a lot from 1' of fresh snow to over 8 feet deep of wind-deposited snow drifts. I did find a rock shark on our descent, so be careful of those.


We dug a pit in a wind-protected pocket along the ridgeline near the summit of Peak 4. We found over 12" of new snow on top of roughly a half foot of facets. We did not find a clearly defined crust layer at our pit location.

Location: Peak 4, ridgeline

Tests: We did two ECT tests and got ECTX on both tests. We did not observe propagation on our ECT test.
