Snow Characteristics Comments

4"-9" of new snow depending on elevation. New snow was right side up with warm dense snow falling first ending up with very low density, cold snow on top. The snow surface were sparkly stellar dendrites stacked up like goose down; blower. Although right side up, the new snow fell on the weak, fist hard facets and the skiing was "punchy" at times, as dense snow fell first during the storm.

Red Flags Comments
Pretty decent visibility today but I did not see any signs of new avalanches, even with binoculars. I experienced a fair amount of audible collapses but no cracking in the new snow. Very poor snow pack structure.

Comments

I traveled the north half of the compass from 7400-10,200 ft. Slope angles to 32°.

Granted my ECT expressed no propagation and there were no visible signs of avalanches but the snow pack structure is very poor and is just waiting for additional weight or a trigger. Additional snow tonight and tomorrow may tip the scale?

On the north half of the compass low and mid elevations are still thin and the pack is very weak at those elevations. South aspects melted off quite a bit before the storm and below 8500 ft there is little to no snow.
