Avalanche Summary

Over the weekend, there were several rider triggered wind slabs from smaller wind loaded features. Mostly small (size 1) with a few large ones (size 2). Small wind slabs continued on Monday.

Read more about conditions in the field team's report from Monday.

Snowpack Summary

Around 10 cm of new snow redistributed by southerly wind lies over a crust that goes up to 1250 m in the shade and to mountain top on slopes that get the sun. Good riding can still be found in sheltered slopes away from the sun.

The mid-pack is generally well settled, with crusts buried around 50 cm, and another near 130 cm deep.

The lower snowpack is facetted, but hasn't been a problem.

Below 1100 m the snowpack is wet and losing strength.
