Triggering large avalanches remains possible.

Assess smaller terrain features before you consider entering larger slopes.

    The moderate Southerly winds have redistributed the recent storm snow and has formed slabs in some locations. As you transition into tree line and the alpine, be mindful of changing conditions and signs of instability like cracking, whumpfing or a hollow feeling below your feet.

Avalanche Summary

A suspected skier triggered sz 2.0 in Lone Pine on Sunday. No perceived involvement.

A few very small natural loose dry avalanches were observed today from steep solar aspects.

Friday, a few natural avalanches up to sz 3 were observed from steep, wind-exposed alpine terrain.

Snowpack Summary

40-60cm of settled snow overlies a layer of decomposing stellars (large new snow crystals), a crust on solar aspects, or a thin layer of facets. Wind effect can be found in the alpine and into tree line.

The mid snowpack is generally strong, however the deep persistent weakness of rounding facets and a decomposing crust remains at the bottom of the snowpack.

Weather Summary

A mix of sun and cloud for Monday with a chance of convective flurries in the afternoon. Alpine temps will range from -10 to -15 with a freezing level of 1000m. Winds will be light from the South.

Similar weather for the remainder of the week.

Terrain and Travel Advice

  • Start with conservative lines and watch for clues of instability.
  • Carefully evaluate steep lines for wind slabs.
  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
