Observations are limited this time of year. Please consider filling out a MIN report if you do head out in the backcountry! ð
Snowpack Summary
Expect early-season conditions with a shallower-than-average snowpack. At treeline depths are between 60-100 cm. Below treeline, snowpack depths taper off quickly.
Surface conditions are variable. Surface hoar growth has been reported in many areas. A sun crust can be found on steep south and west-facing slopes, and wind effect exists on exposed terrain at treeline and above.
A crust with facets below exists 10 to 20 cm above the ground.
