Wind loading on Seattle Ridge until about 11:30am from a NW wind direction.
Recent natural avalanche on Seattle Ridge above Granite Creek camp ground.
Clear skies
Cold, but inverted. 15F at road, 20's at higher elevations
Winds on Magnum were from the East, 10mph
No Precip
1000'- 1500' - 1cm surface hoar and near surface facets
1600'-2800' - near surface faceting where snow was loose or a thin (5mm) wind skin in areas exposed to wind
At road level there is 10" of snow
10-20" of snow until about 2000'
*Snowpack is thin along the NW shoulder of Magnum, 10-20" total. Found a thin crust near the ground in all hand pits, but only found the buried surface hoar layer in a few hand pits along the ridge. Probed around onto the West face and found a deeper snow pack, A 100-130cm (3-4 ft.) Dug a pit at 2545' and found the buried surface hoar 15"(40cm) below the surface. Pit showed poor structure and tests still indicate propagation potential, but required strong force. CT23, ECTP25, ECTP28 (SC)
The first 12" (30cm) of snow near the ground was still moist melt freeze grains... likely the reason glides are active right now.
