Start on small, low angled features to assess how the snow is bonding.
Recent snow will take time to bond with the old surface.

Avalanche Summary
Saturday: Avalanches reported in the pine pass area. Natural and remote triggers in a variety of terrain and at all elevations. Check out this MIN for more information.
Friday: Touchy storm slab conditions were reported in the Pine Pass area with remote triggering of small steep features .
If you venture into the backcountry, please consider submitting a MIN post.
Snowpack Summary
New snow continues to accumulate across the region adding up to 15 - 30 cm of new snow, accompanied by strong southwest alpine winds. This has created deep deposits of new snow and fresh wind slabs in exposed terrain.
New snow has buried older wind-affected surfaces in exposed terrain, or surface hoar, and a faceted upper snowpack in sheltered areas. Layers formed during dry conditions in January are buried approximately 30 to 100 cm below the surface. These consist of surface hoar, faceted grains, and/or a hard crust, and could become a source of instability with the addition of the new snow and warming temperatures.
The lower snowpack is generally well-settled.

Terrain and Travel Advice
- Use increased caution at all elevations. Storm snow is forming touchy slabs.
- Use small, low consequence slopes to test the bond of the new snow.
- Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
Problems
Storm Slabs
New snow, combined with strong winds and mild temperatures, continues to create reactive storm slabs. Weak facets and/or surface hoar may persist beneath the recent snow, increasing storm slab reactivity.
Aspects: All aspects.
