Bastion Pks

From slopes below the Assault Glacier, move right about 500 metres then ascend directly to the summit via a series of linked snow gullies.

The steep spur opposite Banfield Hut provides a direct route to the plateau north-east of Bastion Peaks. Alternatively, travel up Jagged Stream towards the Assault Glacier and traverse below the rock face to the basin. A cone of scree leads to a prominent couloir (watch for rock fall). From within the couloir, move right above bluffs and onto the North East Ridge, which offers easy climbing to the summit.

Originally climbed via Mt Medhurst from a camp at Washbourne Hut. From the col between Mt Medhurst and Bastion Peaks take the north spur directly to the summit.
