From the Murchison Glacier, head up the stream draining the Harper Glacier on the true left. The head of this stream is surrounded by bluffs, but there is a sloping, bouldery shelf running through them that begins at 1800m, grid ref BX16 915 763. This leads up to 2000m at about grid ref BX16 918 762. Gain the col south of Pt 2429m and ascend the straightforward rock ridge.
From Armadillo Saddle, climb scree and snow slopes to the summit.
A good ski touring option from The Ant-hill heads north to the saddle south of spot height 2429m. Ski around the spur of this point on its eastern side to gain the glacier basin east of Mt Richmond. Then ascend towards Mt Acland and gain access to the Aida Glacier via the small notch at about 2400m.
