It appeared that a few inches had fallen and covered the road on our travels up from the Winter TH on snow machines. As we traveled through Geyser Pass to the East side of the range, we were greeted with a lot of deep, mostly unsupportable snow. We found ourselves punching all the way to the bottom of the snowpack at times with not only our boots, but with the snow machine tracks. We did stop to dig a pit and found some things that certainly caused alarm. Most notably, a very reactive slab near the surface of the snowpack. We experienced a notable collapse in a small meadow when we stopped our machines close together and also noted cracks propagating around our snowshoes as we stomped around to recover our powder-hungry machines. The snow depth was incredibly varied in our travels and we noted depths from 55cm to 125cm in sheltered meadows. We also observed somewhat recent avalanche debris that had crossed the road on Mellenthin's Eastern flanks in multiple areas. We also noted old roller balls on Southeasterly, sun-exposed slopes.
