Several days ago, I reported ECT’s failing on a thick 5 mm depth hoar layer. Yesterday, Ned Bair reported ECTP21 for a one meter and two meter extended column test at 10,300 ft. on a slope similar to my tests. Compression tests yielded similar results with sudden collapse on the depth hoar layer. No signs of recent avalanches, whumpfing or cracking were observed.
Snow temperatures in the upper meter of the snowpack near the Hose today showed snow temperatures close to freezing or 0C. A few ice masses were observed, showing that surface melt has traveled through the March snow and into some of the crust/facet combos that formed during and after the small impotent storms that characterized most of the winter storms.
