Snowpack Observations
Observed 12/8 BSH ~30cm down in most terrain traveled that was not densely forested. In the limited locations where BSH was not observed, a strong, rightside up snowpack exists. Thin (1-3cm) and breakable surface crusts were present on solars and steeper E and W facing slopes. Lower angled and sheltered W-N-E aspects hold settled powder at the surface. A new crop of SH is forming in sheltered terrain.
