Solo by left-hand route. About mid-way up had to cross a band of melted out loose stuff before getting back onto snow about 100 from the ridge. All by myself on the summit.
Summited using "East Ridge via Alpine Lake" route. Dropped down to the glacier route from the summit plateau. Encountered some sketchy slush up near the east ridge.
the Glacier route after doing North Peak earlier in the afternoon. Longish day with approach and setting up camp. Setting off huge wet slides earlier in the day on the SW face of North Peak, Glacier route was much better (it was later in the day).
Did the Y couloir in 2007.
