At 2800' on E and NE faces under the 4232' highpoint above Lonesome Mine we encoutered a really hollow snowpack. Pole probes found a medley of crusts and soft layers with a thick (20cm?) layer of "empty feeling" facets at the base. We tiptoed one at a time until on SE aspects at 3,100' and the snow got firmer and probe test didn't fall into a void below.
No obvious instabilities noted on the slope we hoped to do turns on. But, all the suspect layers mentioned in the forecast were present.
