Mt Johnstone

To reach the South Ridge, begin a rising traverse 1 km down valley from Sinclair Bivvy. Follow cones of scree then rock gullies and grassy slopes. When nearing the basin below the low peak, cross the stream and gain the lower portion of the western ridge leading to the low peak south of Mt Johnstone. Traverse gendarmes and detour onto firm red rock slabs before reaching the low peak. A short easy traverse leads to the high summit.

The glacier south of Mt Johnstone can be reached either via the side creek north of Lawrence Hut or from the creek south of Outlaw Stream. Follow the glacier to a col at the foot of the South Ridge of the low peak (2238m). The ridge is time consuming until the low peak is reached, but is straightforward from there to the high peak.
