Bottom Line

We observed two primary weak layers (or potential weak layers) of note. Weak snow at the ground, although very thin in this location, seemed likely to be more of a concern above 9,000' in steep, shady terrain. The snow surface was also very weak. Snow on 11/25 may be enough to preserve this week layer in some locations but only time will tell.

Pit Two: 8,900', NW, 32*, HS = 70 cm ---- larger surface hoar at the snow surface, "dirty-looking" layer about 40 cm off the ground. Older October facets (5 cm thick) present. CT23 and ECTN23 @ the ground.
