Avalanche Summary

On Saturday, there was a small (size 1.5) natural storm slab near Castle and a few small dry loose avalanches.

On Friday, riders triggered several small storm slabs and dry loose avalanches.

Snowpack Summary

Up to 20 cm of low-density snow fell on Friday and Saturday, accompanied by light to moderate northerly wind.

The new snow overlies 20 to 40 cm of mostly faceted snow sitting on a weak layer from late January. The weak layer consists of a crust on sun-exposed slopes, and a layer of surface hoar or facets on all other aspects.

The mid and lower snowpack is generally well settled.
