Three Guardsmen - north side

Wind alternated N-S throughout the day. Moderate S in the morning, shifting to light N in the afternoon.

First column failed at CTH22, down 80cm, sudden planar on a knife penetrable ice crust sitting atop a layer of 2mm facets. Second column yielded a CTN - we couldn't duplicate the failure even with extra-heavy blows on the shovel. That said, the snowpack still exhibits a high, mid-winter temperature gradient with 10-15cm of fresh, fist density storm snow atop a mix of knife crusts and 1f-4f faceted layers. A knife penetrable melt-freeze crust sits about 20cm below the surface and appeared well bonded to the upper 5cm of wind press, and 15cm of storm snow.

Natural avalanches running the full length the the couloirs along the SSW, highway facing side of Three Guardsman. 12-15cm of storm and inter-storm interfaces running on top of what was likely a dense wind/MF crust.
