March 21, I left the trailhead (Upper Dungeness, across from Tubal Cain trailhead) at 1230. My Prius had chains on for part of the drive, just barely enought clearance with the snow. The trail had snow starting at 4500 feet. Microspikes were sufficient. Real snow started at 5000 feet, and I wished I had my backcountry skis. I was postholing up to my knees consistently, but deeper sometimes on the east aspect in the shade where the snow was more powdery. But it wouldn't have been a good ski tour, as I would have had to take the skis off many, many times due to wind-swept bare areas.
