Nope, never got that far. It was quite the drive (5 hours) just to get up to the lake trailhead for the climbs on the south side. Got the Randall guide with me right here, and it doesn't reference any climbs on the north side. The two west side climbs (West Face Flake Route, 5.7+ and Sunset Dihedral, 5.9-) were something I always wanted to check out, though. You thinking next year...??
