Weather

Warm temperatures throughout the entire tour. Light winds from the northwest and seemed to increase throughout the day.
Peak 4068' @ 12:00 3200' Calm winds, Overcast skies, 40F and no precipitation. Extremely poor lighting for part of the day.

Snow surface

South-southwest facing slopes had a breakable sun crust up to 8cm in places. None of the snow seemed to be wet while traveling. On east and north facing aspects snow seemed cold and dry with some wind effect near ridge tops. On northerlies snow was denser than expected but overall good ski quality.

Snowpack

We dug on a east aspect in a shallow location. The snow structure was moderate with a weak interface 20cm from the ground which seems to make a great bed surface. On top of this bed surface sits a thin layer of rounding facets, and slab resting on top. The overall strength was moderate and propagation potential seems low.
