Snowpack Summary
Anywhere from 5 to 10 cm of new snow may be sitting on a crust that exists up to 1850 m in the Wells area. This new snow is likely being redistributed by northwest wind in exposed terrain.
A layer of surface hoar and/or sugary facets may be found sitting about 20 to 40 cm below the snow surface. This layer is likely more of a concern above 1800 m where there is no crust capping it. Wind slabs forming over this layer in the alpine may be more reactive.
The middle and lower snowpack is generally strong with no weak layers of concern.
