Via the ridge south of Rough Creek

From Rough Creek (Route 3.2) climb through the bush and scrub of the ridge immediately south of the creek. Traverse left (south) across scree about 50m above the scrub line into a gully. Cross the creek in the gully and work up through the snowgrass bluffs to the south to reach a ridge with a clear gully on either side. Climb straight up the ridge until it peters out level with the snout of a small glacier descending from Plunket Dome. An easy traverse leads across to the glacier, the south side of which is then followed up to Governors’ Ridge, about 350m above Cascade Saddle. This route would probably take about five hours to Governors’ Ridge. It was investigated in 1954 as a possible alternative route to the Dart, and remnants of a cut track may be found below the bushline.
