Snow Characteristics Comments
Smorgasbord of crusts. Some solar crusts have a thin skiff of facets just above; some protected polar aspects hold recrystallized snow (but not that loose).
Travel was from Tibble Fork reservoir at 6400' north to the Silver Lake Highway; topped out at 9400'. Descended the Other Runs to the east back to Silver Lake Flat.

Problem #2 Comments
HS roughly 120-140cm up to 9400'. Basal facets seem dormant at this time with 4F+ hardness. See profile below.
This is way different than the south side of AF canyon and along the north side of Timpanogos (See Meisenheimer report from 1/22/25 and Hardesty report from 1/15/25 and Gagne/Costa report 1/16/25 from UFO Bowls.
The Timp Divide snotel site at 8170' (see them all HERE) is currently 58% of median (see below) and the coverage (see photos of Box Elder and the north side of Timp) look as if it were Thanksgiving or early December.
