Quick Observation

A nice day skiing at log cabin. 40cm of snow now sits on the ground at the parking lot with a supportive crust down 10 cm. Recent westerly winds have redistributed the weekends new snow at tree-line and in the alpine, where we found an average snow depth of around 1m. Some recent avalanche activity out of steep wind loaded terrain produced wind slab avalanches up to size 1.5. We found good skiing in sheltered terrain but a couple of crust facet layers in the upper 80cm of the snowpack were enough of a concern to keep us on low angle slopes.

Weather

Mainly westerly winds increasing through the day, with light ridge line and down slope wind transport evident. Temperatures were inverted through the day with highs of -15 at 900m and -9 ant 1400m. Tutshi lake remains open with lots of new SH formation along the highway corridor near Powder Valley.

Snowpack

Snow cover is highly variable depending on elevation and aspect. Below tree line the snowpack remains below threshold depth for avalanches. Wind exposed terrain is scoured to ground in places. Overall the The snow pack is structurally suspect with several widespread Crust/Facet layers in the upper 80cm (See snow pack photo). Interesting to note: although we did not get any significant results in our snowpack test part of our group caused a soul puckering whumph (think an artillery round) as they moved off the slope and crossed into a thinner snowpack area.
