Regions: Glacier.

The sun should soften up firm surface crusts today.

Beware of glide cracks that are widening, threatening to release an entire winter's snowpack to the valley bottom.

Cornices still linger up high, like ominous bowling balls looking to roll.

Weather Forecast

Mix of sun cloud today, followed by increasing cloud Tues and unsettled, showery weather Wed/Thurs

Monday: Sunny with cloudy periods. FZL 2000m. Wind W 20-35km/h.

Tues: Mainly cloudy. FZL 1800m. Winds SW 25km/h

Wed: Cloudy with flurries, 5cm. FZL 1900m. Winds SW 25km/h

Snowpack Summary

The snowpack has undergone numerous melt-freeze cycles resulting in several crusts in the upper snowpack on all but high (>2400m) N aspects, where one can still find loose, dry snow. Check out this link for more info on spring conditions.

Avalanche Summary

Saturday, a natural cornice release occurred on a north facing path of Mt Macdonald. The cornice chunks that dropped did not trigger an avalanche.

A natural size 2.0 glide slab released on Thursday night in Mounds (South aspect of Mt Tupper). Numerous other glide cracks are widening, with the potential to fail in the immediate future.
