Mt Ian

From Boys Col follow around the base of Tiber on the north-west side. A snow couloir leads to a rocky ridge from where a traverse down and across a further couloir to the Main Divide allows a crossing of a col to the north-east face. The top is reached up a final couloir.

Alternatively, the long grassy slopes referred to under Ferrier Peak give access to snow slopes below Ferrier and Bernard Peaks which can be crossed to the snowfields above the Blue Duck Glacier. This in turn leads to a steep ice slope which can be followed back to the main ridge and thence to the summit.
