Weather
Broken skies becoming partly sunny.
No precipitation
Temperatures in 20Fs to 40Fs (at road level)
Winds were light
Snow surface
Supportable crust to our high point at 2300'. Distinct runnels below 2000'.
At 3 pm on our way down surfaces with any solar tilt had started to soften and become punchy. Surface crust at 1100' on easterly slope had disappeared. Pole and skis easily sank down into saturated snow.
Snowpack
Below crust at 1000' and 1500' there was wet snow "blue goo". Below the crust at 2000' and 2300' the snow was moist.
