Thanks for the info folks. We went up on Sunday-- left the parking lot at 6:30 am, early enough to be able to enjoy rain and fog on the entire ascent/descent. It cleared after the climb. Brilliant timing!
Nevertheless it was good to get out there. Of course with 50-100ft visibility all day, it was sometimes unclear exactly where we were! We managed to locate some snow in the SE gully route and scampered up. (better snow than slippery rock in the rain) The last 30M or so was low 5th class rock, solid enough with occasional pro. Above the notch it was windy, scrambly, and very dramatic as the clouds raced by. The gully was the last of the interesting climbing so we called it a day.
Visibility remained 50 to 100 ft all day, until about 2pm when it opened up while we were hanging out at Snow lake eating lunch. Summit of chair stayed fog-bound the whole time.
Good times!
