South East Ridge

From Wright Col traverse round the Birley Glacier and snowfields to the south-east ridge. Alternatively, from the bivvy at E40 488 108 on the ridge to Esquilant Bivvy, gain the snowfields on the glacier under the East Peak and drop down to the col north of Black Peak. An alternative route is to gain the South East Ridge higher up above a prominent rocky buttress sticking out of the glacier.
From Lennox Pass or the route from the Kea Basin track to Lennox Pass, gain ledges under and east of Peak 2026 at 1650m, then sidle right to the ridge leading to Black Peak. Traverse Black Peak and descend to the col. Traverse snow slopes on eastern side of ridge crest until regaining ridge. The route over Black Peak requires caution because of very loose rock. Alternatively, sidle round on the snowfields on the south side of Black Peak to gain the col and the south-east ridge.
