I climbed up the cattrack for a couple early laps, knowing that conditions were going to deteriorate by the afternoon. A couple of dense inches on top of a foot or two of nice cold snow. Not too many turns required, but still pretty fun and ecscapable. I headed back up to the ridge beyond skyline lake for lunch. No heading over the north side this time. Alone, yellow light terrain, red light weather....it was still tempting. I could see (again) how bad decisions start to grow. I got out my shovel and saw to put something productive in motion.
Pit at 5200 feet. N aspect, just over crest of ridge. Slope about 20-25 degrees.
The fresh deposits were mostly columns and dendrites -- it was just puking them! The Dec rain crust was about 170 cm inches below the surface. 0-15 cm was frsh, dense, warm. 15-80 was fresh, light and cold. 80-160 was soft-med, increasing dense with depth. Below this was 5-10 cm of very sugary, non-cohesive facetted snow, om top of the rain crust. the first few cm of the crust were somewhat facetted as well. Very easy sheer and 2 tap compression in dense surface layer, and at base of cold, fresh snow, but both with poor (irregular) sliding surfaces. The lower 80 cm generally moved as a unit, with moderate shovel sheer and/or 3 hard whacks. more imporatantly on a very smoth sliding surface. the blocks slid easily into the pit, even on this low angle.
I skiing back down to the parking lot in snow that was getting way too deep and dense to even try to turn.
