These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Snowpack Observation
Flagpole Peak

Echo Summit Area
Open east facing slopes around 7000 feet had a completely supportable crust at 9:00AM There were several large old wet loose slides on and adjacent to Flagpole. At the time I took this photo there were plumes of wind driven snow swirling around the summit and over the old wet loose debris. On a more NE aspect at about 7500 feet there was still nearly a foot of cold powdery snow. Looking towards Ralston. The winds were strong near the summit and blowing moderate amounts of snow. The SE side of this generally E facing gully had evidence of previous wet loose activity that ran for nearly 1000 feet. Professional Observer

Snowpack Observation
Elephant's Hump

Carson Pass Area
10:45 am: Deep ski penetration in to wet snow on sunny NE aspect terrain around 8,000'. 10 am: Deep boot penetration into wet snow at the trailhead. This open E aspect near treeline had much better supportability than the other slopes around it. Forecaster

Snowpack Observation
Elephants Hump

Carson Pass Area
Ankle deep boot penetration on an E aspect at 8000 ft. at 12:45 pm. Propogation saw test targetting the Feb facets (the layer my finger is pointing to). The test failed about 1/3 of the way through the column (where the saw is stuck into the block) indicating that fractures can propogate along the weak layer. (PST 50/150 END down 146cm) The Feb. facets that have rounded but still remain a loose layer buried deep in the snowpack. Forecaster

Snowpack Observation
Mt. Judah

Donner Summit Area
Snowmelt has exposed many more rocks and other obstacles especially on sunny slopes. This is a west aspect at about 7400 ft. Some fissures are starting to melt out above the E facing slopes near the summit of Judah. Large areas of bare ground are now exposed on the south facing slopes. Finding continuous snow on south facing slopes has become more challenging. The snow on sunny slopes started to get unsupportable around noon on S facing aspects. Boot top deep wet snow near a waterfall that has melted out at about 7600 ft on a south aspect. Forecaster

Avalanche Observation
Rubicon Peak

West Shore Area
A ski cut on this small E-facing test slope triggered a small sluff of wet snow. It stayed small because the slope was small. A ski kick on the same test slope triggered this 7 ft diameter pinwheel moments later. Looking up the small slope that produced the 7 ft diameter pinwheel. Thin, weak refreeze on N aspects at 9:45 am on Rubicon. Rollerballs, pinwheels, and wet loose activity on the E face of Jakes Peak. Clouds over the lake indicating colder air below the clouds and warmer air above the clouds. This inversion remained low and the cold air did not extend much above the lake level. Forecaster
