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.
Both pits were along the Titus Lake trail. Here is a summary, more detailed notes are attached.
Pit One: 9,020', SSE, 29*, HS = 43 cm ---- surface hoar at the snow surface sat above a sun crust. One other stout crust about 20 cm off the ground. No October snow.
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.
No problems in the terrain we traveled.
