Areas away from the sun and wind offer the best riding.

Snowpack Summary

Southwest winds at all elevations may have redistributed snow that fell last week. Storm snow tapers to a rain crust below 1700 m. Solar aspects at treeline and below are coved in a melt-freeze crust.

A melt-freeze crust with facets above can be found 50 to 120 cm deep. It has not produced any recent avalanche activity in the region, however, professionals are still tracking it to watch for signs of it becoming an active problem.

The mid to lower snowpack is well-bonded. Currently, we are not seeing the same basal weak layers and reactivity that many of the neighboring regions are experiencing this season.
