Snowpack Observer Allen Giernet Keep me anonymous if published no Location (general area) Near Mt Baldy resort Date (yyyymmdd) 20130309 Time 10:48 a.m. Road conditions to area clear and dry Temperature not measured Sky clear (no clouds) Wind speed Moderate (17-25mph Small trees sway/ flags stretched) Wind direction NW Slope aspect North West Slope angle 26° Elevation 7900 Snow depth not recorded Boot/ Ski penetration variable Precipitation None Activity, recent avalanches No Whumphing noises, shooting cracks. collapsing no Rapid warming no Obvious avalanche path yes Terrain trap yes Comment Two ECT tests were performed #1 ECT 6 Q3 on new snow interface, ECT22P 50cm ⇓ Q2 on wet facets #2 ECT 5 Q3 on new snow interface, ECTN probably a false stability due to foreign influence on the snow pack here. The snowpack in this area had a temperature gradient in the upper 30cm with an isothermic snowpack to the ground. The facets were wet and rounding. Signs of wind loading following the last storm were evident on mostly Southerly aspects. When we returned the following day the winds had changed directions and we could see the transported snow being redistributed around the mountains mostly on the Northerly aspects. There was some soft slab formations with the wind transpoerted snow. We saw pinwheels develop later in the day at lower elevations.
