The Sisters area is a complex section of the mountain. Leading south from the summit is the upper portion of the Sisters Ridge, which spills into two subsidiary ribs further down. One of these, the steeper of the two, leads due west and ultimately merges with the West Face, the other leads directly down to the top of the Okahu Gorge. Both provide fine introductions to the traverse of the upper ice towers. South again, and separated from the Sisters Ridge by an easy snow gully (the Sisters Gully) lies an isolated block, which contains one short route, Noteworthy more for the exotic ice formations found on the first ascent, than for any particularly distinctive line.

| Lion Rampant, WI4 | WI4 | |||||
Down and right of the last route is a short groove leading to an obvious ramp cutting right to left across the wall. Once established on the left edge of the buttress, from there break through the icicles to finish. |
