Most interesting feature of the pit was consistent failure in Compression Tests and a Shovel Tilt Test on a layer I couldn't see or feel within the newer snow. The failures occurred approx. 25cm deep, and despite looking closely I couldn't identify a clear layer. Final photo shows a closeup of that portion of the snowpack with a crystal card behind it to add contrast. Perhaps there is a slightly darker line there indicating a thin layer of buried surface hoar, or perhaps just a discontinuity in the new snow as it fell?
