Observations

We observed 20 cm of new snow on a stout, supportable crust. Near and above TL there was significant wind transport with drifting and wind buffed areas. We dug a pit and observed a variety of layers in the snowpack with an HS of 115 cm. Unfortunately pretty similar depth (85 cm) to what we observed on November 7th in the same region. Ski conditions near TL were pretty good while keeping in mind early season snow pack considerations like creeks, gullies, trees and the like. The best skiing for soft turns was on lower angle slopes in slightly treed areas at high elevation. The cold temperatures preserved good snow. While there was significant evidence of wind affect on the new snow the weather was calm during our tour.
