Route & General Observations

On the showboat ridge approach we turned around due to intense winds and active wind loading. At rescue meadows we dug pits and later in the day skinned back up and descended through the trees down slowboat. Active wind loading and snow accumulations throughout the day. We avoided slopes greater than 30 degrees with recent wind loading.

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

Obscured skies with increasing snowfall throughout the day. Moderate NE winds with stronger gusts near ridge-lines.Temperatures in the mid-high teens.

Snow surface

4" of new snow accumulation. Storm slabs building on wind loaded slopes.

Snowpack

At 2,000' on a SW-aspect in an open meadow the total snow depth was 200cm. Extended column test results revealed no propagating test results with ECTX. However, a propagation saw tests propagated down 70cm below a melt-freeze crust on facets with PST 25/100 End. We suspect this to be below the end of year crust.

We also found a layer of buried surface hoar below the Jan. 14 drizzle crust down 80cm. This surface hoar likely formed before Jan. 13th and was buried after that.
