My friend Jim and I had a couple good days on MSH. We left Seattle about 9:45, checked in at the Lone Fir "Resort" before 1 and his the trailhead at Marble Mountain Snopark about 1:45. Our goal was an overnight stay above snow line and an easier summit day, but because we started so late, the snow was plenty slushy when we got to it. A lot of shin- and knee-deep post holing. As a result, Jim led us over the rocks most of the way on day 1, which was slow, meticulous, and more demanding physically and mentally that I wanted. Still, a gorgeous day in the mountains is nothing to sniff at.
Above snowline around 5,000 feet we found it to be a bit of a slog and kept to others' boot tracks. Not a lot of others coming down or going up...
Started getting super windy about 5,500 ft and we found a nice bowl with a fairly level spot about 6,600 ft off to the left of the main trail. Windy windy windy and once the sun was behind the ridge to the west, pretty chilly, too. After a wind-battered night (others we spoke to who camped down lower said it was peaceful as all heck!), we started at 7:35. The snow had solidified overnight and was crampon-perfect. Splendid, glorious, clear morning and great climbing. We summited at 9:05 or so in heavy, dense clouds. And wind. Bummer that we had no views.
Glissaded down--very icy chutes from the summit down the first 500 feet--hard to control one's speed. But the glissade chutes got better down lower as the snow warmed a but and the sun came out. Beautiful day to descend--crossed paths with 50-75 people doing it in one day, slid about as far down as humanly possible, and hiked out the rest. Some minor confusion picking up the trail on the way out a couple times, but got to the car 1:05 and back to Seattle by 5 pm.
