1cm surf hoar at Lulu

"At 9410ft, NNW aspect, 10 degree slope, we found HS 75cm. The general structure seems right side up. There are facets at the bottom 20cm or so, but they are wet, and seem to be rounding. An ECT gave us ECTN20 at 40cm down." Photo: N. Mattes

The head of Beaver Creek was scoured nearly to dirt and the cornice is quite large there already.  We noted one small wind slab avalanche just below it.  We found a similar avalanche in Second Yellowmule that again appeared to be from wind loading.  Both appeared to be several days old.

Mark investigates a thin and weakening snowpack. Despite air temperatures near 40 degrees F mid-day on Monday, the snow surface was 21 degrees F. These large temperature gradients will drive rapid faceting. Photo: GNFAC
