Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

A couple inches of new snow from pervious 48 hrs. Winds were calm everywhere we were today. Though did notice active flagging late in the day on the high peaks looking south toward Grandview and Bench Peak. Temp was 17F at the highway and warmer at elevation.
Fog layer lowered and hung at about 2400' thru most of the afternoon. Grey day below, blue sky and sunshine above!

Snow surface

Widespread 2-3mm surface hoar 2,000' and above deposited on fist hard surface. Since Sunday (last I was up here), still very little wind effect in this zone.


The top 24" has settled a little since Sunday but there still isn't much of a (widespread) slab to speak of above the 1/28 buried surface hoar.
Dug a pit at 3400' on a west aspect. 27 degree slope. CT18, ECTP21 on buried surface hoar 40cm down. First hard above the bsh. 4F then 1F below in the top 100cm of snowpack.
Continued series of taps on column below bsh with no results below bsh layer.
We did find the ground at this location. HS = 380cm (12.5')
