Overview & Approach
From Kangaroo Pass traverse E (slightly below the level of the pass) and find a low point along the ridge where you can cross N (between Walaby & Little Finger) over into the basin S of Half Moon. In this photo from Klenke you can see the approach-route crosses the snow field S of Wallaby and over a shouder to the talus field leading up to Half Moon. From here make an ascending traverse N towards the (now visible) South Face across snowfields and or talus, depending upon time of year, to the base of the Peak.

Find the beginning of the route near the E side, See Here, of the Face at the lowest toe of rock protruding from the S Face, scramble up ~100' to the first belay location.
The first pitch or two climbs bottomed-out, flaring and rounded cracks (these are the hardest climbing). Initially the rock is of poor quality but as you climb higher it becomes better and easier to protect. There are several ledges for belay stances located along the way, take advantage of them. The final pitch (upon the face) begins, from a good ledge at the base of a shallow & wide chimney, with a long step-across. Climb the chimney to it's top and reach the ridge N of the summit. From here it's Class 3 or easy Class 4 to the top. Descend the route or if carrying all your gear with you and if you're familiar with the North Ridge route you may descend that (saving a couple of miles travel on the return in the process).
