Avalanche Summary
On Saturday, several natural and human-triggered wet loose avalanches were reported in steep features at treeline and below, up to size 1.5.
A rider triggered size 2, persistent slab avalanche was reported. This avalanche occurred on a west facing slope at 2000 m. See MIN for details.
Snowpack Summary
A melt-freeze crust covers the snow surface on all but high-elevation north aspects. This overlies 30 to 60 cm of snow that sits above a crust in many areas or surface hoar/facets in wind-sheltered areas.
A weak layer buried in late January consisting of surface hoar/facets or a crust, is buried 50 to 90 cm and remains a lingering concern. Below this, the mid and lower snowpack is generally settled and strong.

Terrain and Travel Advice
- Be aware of the potential for large avalanches due to buried weak layers.
- Be alert to conditions that change with elevation and sun exposure.
- A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
Problems
Persistent Slabs
A weak layer of consisting of a crust and/or facets is buried 30 to 60 cm. Recent avalanches on this layer indicate it remains poorly bonded.
