Snowpack Summary

Recently, warm temperatures created moist surface snow on sunny aspects and on all aspects at low elevations. Where a re-freeze has occurred, a crust now exists. Surface hoar (5mm) has been forming on that crust at treeline and below. Recent storm snow appears to bonding well. A facet layer which formed in mid-January has gained strength. It showed hard, resistant planar results in a compression test at treeline in the Hankin area on Sunday.
