From the upper Gunn River, head up tussock slopes towards a buttressed spur on the true left
of the stream draining the Wigley Glacier. A steep but negotiable gully (requiring scrambling
on bedrock), about 100 metres before the Wigley River issues from a slit gorge, leads through
bluffs to rocky knolls above and gravel flats further up the valley. Lower ice shown on the map
below 1600 metres has now largely gone. From I35 958525 / BW16 858 909, gain access to the
upper Wigley Glacier via a diagonal ledge that doesn’t look promising from below on the true
right of the icefall. This gravel ledge leads easily up beside the icefall to where the ice and upper
glacier can be accessed. Crevasses may make this more difficult with ice recession and later in
summer. From the upper glacier, snow slopes lead to the ridge and the peak is a bit beyond that.
