Snoqualmie Pass

Dec. 19, 2015, 2 p.m. PST

Snowpack: 150cm snowpack depth at about 3700 ft. Snow is largely medium to low density above a solid, thick rain crust near the base, which is on top of what seems to be rounded out depth hoar. At 70 cm there appeared to be a poor bond on a thin layer of faceted crystals between older snow and more recent storm snow from this past week. Did a quick column compression test. Storm snow from the week produced poor shear quality in upper layers. Major collapses in the test: 30cm deep Q2 / 3 collapse in the new snow after 15 hits (10 hand, 5 elbow), and a Q1 shear at a depth of 70cm after 10 more hits (5 more elbow, 5 full arm).

Area Description: West slope, 32 degrees, Snoqualmie East

Avalanches: None visible, no pockets pulled, even on small, steeper pitches
