Sunny, calm to no winds. Temperatures 20s warming to 31 degrees towards sunset.

Snow surface

Low density snow, ski pen 25-30 cm.


Hand pit test on up track generally confirmed forecast and upper 30 cm of snow was not cohesive and did not break on any discernable surface. The only exception was a single wind affected feature on SW fact at ~3520' where hand shear occurred on Q3 plane ~30 cm down in snow pack with approx. 10-15 cm of firmer overlying snow.

Pit dug at 4210' on SW aspect on Microdot ridge.

Height of snow was between 160 and 215 cm. CT3Q3 down 20cm (~200 cm from base of snow) at interface within fist hard snow on what looked to be buried surface hoar. CT15Q3 down 45 (~175 cm from base of snow) at interface between fist and 4F snow. Coarse facets (>2 mm) observed in snowpack at ~90 cm from base of snow. ECTX result on same test pit location as well.
