Quick Observation

Climbed Twisted, starting from the car around 8am. Temperatures were mild and there was calm winds and snow all day. The ice is quite picked out still from all the early season traffic, but fresh lines can still be found. Snow was deep in tree line and below with minimal crusts, but in the paths and on top of the climb there were patchy 4F hardness windslabs. Roughly 5cm of snow between 10am-4pm.

Weather

Snowfall of S-1 to S1 all day, with valley bottom accumulation of 5cm between 1000 and 1600. Calm winds and overcast to obscured sky. Temp of -8 at 0800, rising to -4 at 1600.

Snowpack

On approach and descent, observed no crusts in tree islands but crust overlying a 10-20cm thick wind slab in the midpack. Some supportive travel, with areas of punching through approx 60cm. Some sluffing observed out of steep terrain especially later in the day.
