This pic was taken from the summit of the McArthur Crags. The ridge running NE away from the viewers eye leads to the top of Mt Kerr then the long ridge running E (right) ,not the shorter spur, heads to the headwaters of Olderog Creek. These ridge crests are a large part of the tops travel between the two bivs. See my other photo, "Route down off McArthur Crags..." for a segment of the tops travel in the other direction.
