Avalanche Summary

Our field team reported small skier-triggered wind slabs in steep start zones in the Sky Pilot area on Thursday.

Looking forward, fresh storm slabs will likely be similarly reactive to riders.

Snowpack Summary

15 to 40 cm of new snow sits over old faceted and/or moderately wind affected snow.

A rain crust buried 30 to 50 cm deep appears to be bonding well. The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth varies from 130 to 250 cm at treeline, tapering quicly with elevation.
