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 four days.
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.
Weather Summary
Up to 15 cm of snow forecast by Monday. Light westerly winds switching to northerly, freezing levels at valley bottom, alpine high of -6 C on Sunday.
Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Problems
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 thick to thin snowpack areas.
