South Ridge

Sidle around to the lower Cahill Glacier from Barker Hut. Avoid descending
onto the lower rock slabs, instead using snow/scree ramps to reach the small
buttress on the true right, descending onto the Cahill Glacier icefall ramp
behind it (safer with ice/snow cover). Watch for stone fall from the bluffs
on the southwest. Ascend the head of the glacier to a col, using available
snow or ice ramps on the true left. These connect to the craggy South Ridge
of Mt Davie. In early summer this route can be cut by a series of huge
bergschrunds.
