Signs of Unstable Snow

Observations

From 4000-6000' the snow has been through several freeze thaw cycles and is frozen hard fairly deeply in the morning softening in the afternoon sun. Above 6000' lee aspects have shallow wind slabs over knobby rime ice. Ridges are wind scoured snow, especially above 7600. The big 35 degree slope on the east side of Monitor Ridge above 7,000' had a deep layer of firm crusty wind transported snow.

I saw no evidence anywhere of recent avalanches other than a very few rare roller balls below 4800' . Very small cornice failures did not entrain any snow from slopes below. There were large glide cracks along masses of snow and ice clinging to the east side of steep slopes.
