Well the lower parts of Hasler did not see that 15-25 cm of new snow Friday night. Below 1400 m it never froze, and there was rain in the late afternoon. We rode towards Otto, and the creeks and crossings were all open and tricky. The snowpack in the trees was about 100 cm deep, with 4 cm of wet fresh on top of a 5 cm heavy melt crust that’s poorly bonded to the snow beneath. There are several facet and rime layers in the top 60 cm of snow, and, at least in our pit, the Oct and Nov crust layers are now just one thick layer of facets and trash at ground level. We had results in the low moderate range on ground (CTM11 down 90 SC x2) but no propagation on an extended column test. This rain and melt crust will be the next layer of concern once it finally gets buried by new snow. Precip began about 2 pm. It was wet snow above 1300 m, rain lower down. It rained all the way out to the trucks at dark.

Multiple layers above in the snowpack all seem well bonded, but the bottom 20 cm is a layer of Shmoo, facets and old ice chunks. Sudden collapse on two tests on the 11th and 12 taps.
