Weather

High-thin cloud cover. Calm to light winds out of the South. No new snow and no blowing snow observed. Air temp was measured at just below freezing (-1 C @ 11am).

Snowpack

Average HS was approx 100cm. Noticed large surface hoar on most shaded slopes.

Avalanche

Observed a Loose Snow avalanche on a west facing slope at approx 11,000' on the slope just North of Cemetery. I believe that it ran yesterday afternoon (when it was very sunny and warm). We noticed some more debris running down the slide path this afternoon.
