The thin snowpack is deep enough to hide season-ending hazards just below its surface. Valley bottom conditions are rugged, take your time, travel with caution, bring a headlamp and warm layers, and have a plan to deal with emergencies within your group.

Please post observations (ex: surface hoar distribution and size) on the Mountain Information Network (MIN), as this layer will become a concern once it is buried.

Avalanche Summary

A size 2.5 glide slab release was observed last weekend from Mt. Tupper in the Lens path. Otherwise, no new significant avalanche observations have been reported.

Expect loose snow to sluff in steep terrain.

Snowpack Summary

The snowpack is thin and facetted with an average depth of 30-40cm below treeline, 60-100cm at treeline, and up to 120cm in the alpine in loaded areas. These values are below the threshold for burying rocks, stumps, covering creeks, and bridging crevasses.

Surface hoar 5-30mm has been found up to treeline and is suspected to exist in shaded/sheltered areas in the alpine.

Weather Summary

The ridge of high pressure lingers, blocking any systems into our region until Tuesday.

Expect a mix of sun and cloud for the weekend, daytime highs of -5, and overnight lows of -15. Ridgetop winds will be 10-20km/hr from the SW.
