Observer Comments
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.
Weather
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.
Snow surface
Soft snow surface along the entire route. Ski penetration of 3-6" below treeline, changing to 1-6" above treeline depending on wind exposure.
Snowpack
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.
1500' - Height of Snow (HS): 90cm, crust down 80cm
2000' - HS: 150cm, crust sandwich down 120cm
2300' - HS: 160cm, crust sandwich down 135cm
This glide formed and part of it released on the SW aspect of Lipps in the past three days; it wasn't present on 12/26.
