Small to long running, 1,000 ft. wet slides released yesterday on east and northeast facing slopes in alpine terrain in Rock Creek, Mammoth and the backcountry west of June Lk.
A snowpit dug at 12,000 ft in the Rock Creek area is shown below. The snowpack is close to 5 ft deep- much deeper than the 3 ft snowpack at 10,000 ft. There are multiple facet/crust combinations. Fine grained rounds predominate in the upper half of the pack probably from the early March and end of March storms. The good ol’ Rock Creek depth hoar is there and is 12 inches thick. The crusts had facets under the crusts and ice masses ( flow fingers) in the snow closest to the surface.
