Avalanche Summary

A few small (size 1) avalanches were reported on Tuesday and Wednesday including:

  • Wet loose avalanches on sun-exposed slopes and at low elevations.

  • Human-triggered wind slabs on north-facing slopes.

Snowpack Summary

5 to 15 cm of dry snow may be found on north-facing slopes, otherwise, the upper snowpack consists of various melt-freeze layers.

The facet/crust layer that caused large avalanches in March is buried 100 to 150 cm deep and is unlikely to trigger under the current conditions.
