The glides in Lynx Creek drainage as pictured in the first photo of Heather Thamm's 12/24 observation have multiplied, with one appearing to have released in the past day or two. See photos below.
Few clouds with patchy valley fog turning to overcast skies early afternoon; late afternoon the skies became obscured. Cold objects started riming at this time. Light occasional east winds at ridgeline. Temps warming from 20s to near freezing by late in the day.
Soft snow surface along the entire route. Ski penetration of 3-6" below treeline, changing to 1-6" above treeline depending on wind exposure.
No formal tests; probing revealed a similar structure to further north in the valley, but with what felt like thinner/softer melt freeze crusts than observed in other locations to the north this week.
