Direct Route

Scale scree and bluffs above the Mueller Glacier, to reach the lower Shelf Glacier, beneath and just north of the prominent cliffs of the upper Shelf Glacier. Ascend the lower Shelf Glacier onto a snow face below and to the right of the icecliffs. Use the snow face to reach an arête on the right hand edge of the upper Shelf. At this point the two access routes from Sefton Bivvy join.
