This is a more obscure area in the Valley. You may wish to scope it out first without a pack on a rest day, although once you know the approach it is not that bad.
Hike east from the Mirror Lake trailhead (east end of the valley, beyond Washington Column) for about a half mile. Cross the first series of creek beds and follow them straight up the hill untl a traverse right leads to the base of the left side of the wall.
