Points saillants
Good skiing can be found in terrain that was sheltered from previous winds.
Manage terrain cautiously if the snow surface is wind stiffened, or if a crust can be found below last weeks storm snow.

Snowpack Summary
Wind slabs from early in the week still linger in exposed terrain - these formed from West switching to strong Northerly winds. The February 15 surface hoar/solar crust is down 30-70 cm. This layer hasn't been reactive in stability tests or to skier traffic in the past couple days, but surprised several parties early in the week.
Avalanche Summary
There were a few MIN reports of several small slab avalanches on the steep NRC headwall Thursday.
No new natural avalanches were observed Thurs-Fri.
Early this week there were several reports of human triggered avalanches failing in wind slabs and on the Feb 15 layer - partial burials on Avalanche Crest, Vaux Moraine, wind slabs on Cougar Creek East.
