We climbed the "normal" route up Mount Saint Helens: Climber's Bivouac to Monitor Ridge. I originally thought it would be insane to do it in November, but the conditions turned out to be excellent. There'd been quite a bit of snow in October, so the loose sand that normally makes it hard to get traction was either covered in hard-packed snow or still wet. Temperatures were in the 40s, but the sun made it feel warmer; the wind was only an issue at the very top.
