Adit Ridge

Cowboy North

Just a heads up that we now have a persistent weak layer down 50-100cm esp around 1800-1900m on a variety of asp. This sz2 failed on the convexity at the E end of Adit ridge and ran 225m downslope triggering to sz1.0 sympathetic avies. Deposition to 1.5m. Believed to have run 180303. At tl and btl in widely spaced trees wumphfing, settlements, and shooting cracks are a strong indication this buried surface hoar over facets layer exists. Look for supported terrain and avoid convexities.
