The snow in the morning was bullet proof, and then with the temperatures obviously loosed things up. There is a trench from the lower 2wd TH to treeline. If the temps are low you wouldn't need anything but trailrunners the trench is so cut (but wouldn't recommend it). Traction device was necessary above treeline this morning with the extremely hard snow. Skied off the summit for about 40 yards, then carried the skis for a bit further down. The skis were great for cutting time down on that last two miles from the 4wd to the 2wd.
