Found about 17cm of weak, sugary facets near the ground. They failed in an extended column test but did not propagate (ECTN15). Temperature gradient 0 through this layer indicates increasing stability.

Comments
-The depth hoar still exists, but it looks like this location has gotten pretty warm lately and it's on an E aspect so it's probably more stable than higher, N facing slopes.
-The ice crust wasn't too solid. I'm guessing it formed on top of the Thanksgiving snow during the warm-up around Dec. 3-4. It was not reactive in my ECT.
-The 5 cm thick graupel layer (see photo) could be an issue if it gets overloaded, but for now it's only under a couple inches of new snow.
