Weather
Clear becoming overcast by afternoon
Winds were light in the am building to moderate by afternoon from the N, NE
Mid 20's F
No precip
Snow surface
*Surface hoar found to 3000'. By 2pm surface hoar was getting blown around in wind exposed places above 2500'
Near surface faceting in the top 2-5" of low density snow at all elevations except where winds have scoured ridges
Snowpack
1100'- 2000' - several layers of thin melt freeze crusts in top 10" of snowpack. Didn't dig at this elevations, but could feel with ski poles and quick hand pit.
2000-2400' - thin wafer like crust under 5" of near surface facets
Pit at 2725' - see pit profile, found a reactive layer of intact surface hoar 12" below the surface- ECTP13 and ECTP14 SC- scores showed propagation potential on a smooth bed surface. ~ 10cm of basal facets were found on ground and were not as reactive as the buried surface hoar.
Pit at 2800' - wind exposed area, HS=65, SE aspect, 30* slope, found 15cm of F hard basal facets/rounding facets (1.5-3mm) on ground under 30cm Pencil hard slab. ECTXx2
Active wind loading, North Northeast wind direction
Lenticular's - small lens shaped clouds observed North of Moose Mountain
4-10mm buried surface hoar found in pit (grid squares are 3mm)
buried surface hoar visibile in pit wall
pit at 2725' on a SE aspect of Fresno Ridge
Pit at 2725' was dug just above skier near ridge, adjacent to trees
rounded basal facets (grid size is 3mm)
Pit at 2800' SE aspect
