The cliff directly above the lower tier of cliffs, in the centre of the Cirque. This cliff may largely bank out and become snow covered as the season progresses.
Be very wary of snow conditions in the Upper Cirque.
Via the McPherson Cirque path, and then either up the access/descent route at the left hand end of the lower tier, or climb one of the routes on the lower tier.
Best descent is either over the top to Talbot's Ladder, or abseil the route back into the floor of the Upper Cirque, dependent on the state of the snow above the cliff.
