North West Ridge

From about the 1300-metre contour in the upper Gunn River, head north-west up moraine, then scree and snow slopes, to the crest of the range. Easy travel along the range leads to the summit. To continue to the Callery, follow the range south over normally easy schrunds to Tartare Saddle. A steep spur at I35 912509 / BX16 812 893 can be used to descend to the valley, where the Callery River is normally easily crossed below the lake. Traversing around the lake is really only practical on the true left.
