Weather

More obscured with sucker holes, with low clouds and poor vis above treeline through most of the morning. Sun broke through for brief periods.

Snowpack


10 cm new snow. Poorly bonded

Sun/Mon snow consolidated to about 8 cm layer. Open areas had moist, spongy crust that did not freeze overnight. Supportable with skis flat, but easy to break through on slopes. about 5 cm of less dense, damp snow.

Highly variable upper snowpack, with consistency and layering changing over short distances based on sun and wind exposure. I dug two pits, and found 15 and 20 layers in the upper 1.5 meters of snow.

Notable layers (see photo):
40-50 cm deep, transition from dry-moist recent snow to wet or drained rounds. CTM Q3 on the interface, failed with a slight collapse and then stuck.
110-120 cm deep, obvious old snow surface with lots of dirt, seeds, and needles. CTHQ3 with sudden drops in poorly bonded rounds just under the old surface crust. Would estimate the entire column above over 200 kg/m3.
