Dug quick pit at 10,300ft north facing and protected, same thing I've been seeing for a few weeks now, but the dirty graupel layer is becoming stronger and the depth hoar at the bottom of the pack remains the weakest link. Once again I could not isolate a column without it failing on the facets at the ground on a 35 degree slope. With possible cold clear nights in the near future I would expect to see the surface snow weaken and the crusts break down as time goes on, but I still consider the base of the snow pack the weakest layer, this is mainly above 9600ft on N, NE slopes, everything else just needs a good dose of snow.
