Snowpack Summary
The return of the freezing level at the valley bottom during the night and for part of the day will form a melt-freeze crust on the surface, which may make travel conditions difficult.
In general, the rapid melting of the snowpack in recent days has exposed the ground, primarily at and below the treeline. Below the treeline, snow conditions are now minimal.Snowpack heights range from 10 cm (valley) to 105 cm (mid-mountain).
