Cooler temps, cloud cover, and a trace of new snow will put the spring feeling on hold for the next few days.

Deep persistent slabs may still be reactive to human triggers in shallow snowpack areas.




Avalanche Summary

No new avalanche activity reported over the past 2 days.

On Tuesday a size 2 avalanche ran in the Churchill North Slide path to tree line.

Don't forget to post avalanche observations to the MIN.

Snowpack Summary

Sun crust at all elevations on solar aspects. Facets on polar aspects with unsupportive pockets in shallow snowpack areas. The middle of the snowpack consists of multiple layers of dense wind-affected snow, sun crust, and facets. Depth hoar and basal facets make up the base of the snowpack. Snow depth varies ranges from 60-170cm.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.


Deep Persistent Slabs

An icon showing Deep Persistent Slabs

The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. Large triggers like cornices can still initiate this deep persistent slab so be mindful of your overhead hazard and keep in mind that human triggering remains possible in thin snowpack areas.

Aspects: All aspects.

Elevations: Alpine, Treeline.
