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

Low teens to low 20s, though the sun made it feel hotter. Clear, changing to scattered clouds by late afternoon. Calm except for a light east breeze on top of Wolverine in the afternoon.

Snow surface

Fist hard near surface facets along the entire route, 6-12" from the weekend storm generally over 5-10" of well developed facets from prior to the storm. Ski penetration of 3-5".

Surface hoar (3mm - 10mm) on northerly or shaded aspects . The sun appears to have destroyed any prior surface hoar on south - west aspects along our route. 1cm melt freeze crust on steeper southerly aspects; moist snow on the surface by late afternoon on steep westerly aspects.

Surface hoar was never on a hard surface; always over recent near surface facets.

Snowpack

Informal hand pits were dug on Westerly to Northerly oriented slopes throughout the day. CT 12-17 SC consistently observed, and ECTP 12-14 at the new/old snow interface, down 6-12" from the surface. The 'slab' was generally fist + hardness, with the exception of right off the top of Wolverine, 3000' on a west aspect, 20 degree slope, where the slope has experienced prior wind loading. Here the new snow went from fist -> 4 finger hardness over the fist+ old facets.
