Route & General Observations

Drove through Turnagain Pass around 10:30am and again at 3:30pm after a tour up Sunburst. Visibility was good and we could see a few mid-storm small avalanches (D1-1.5) on specific steep terrain features as well as some debris in very steep and channeled terrain at bottom of Tincan SW face.

Many glide cracks that were visible before the New Years storm were covered and hard to see. We spotted a couple larger glide cracks opening (Lipps and Lynx Creek) and didn’t see any new glide avalanches. The glide avalanche that released on Seattle on Monday 12/31 was not visible or easy to see.

(1/3/18 at 8am) – We receive a report of a large remote triggered avalanche on Seattle creek drainage that occurred sometime yesterday (1/2.) Limited info at this time, but several folks mentioned it was 4′ deep. We are collecting more details today.
