Comments: 
Decided to check out an area of very thin snowpack, and found just that. Before this weekend's storm, this area was entirely facets with a rain crust capping it. Wanted to see how this would react to 18" of new snow. 90 cm of snow in total. No cohesive slab to be found. Two ECTs with identical results, failure at facets near the ground, at 29, no propagation. Light density snow didn't add that much SWE weight, but I don't trust this snowpack in this area for future storms with additional weight.
