It extends in the shape of a shallow bow between Miette River and Grant Brook and forms the northern wall of the valley of Yellowhead Lake and Fraser River." (BC-Alberta Boundary Report, Part II, 1917-1921, p.25). Summit ridge extends 5+ miles, from Tête Roche westward past Leather and Bingley Peaks.

This is likely the feature that Dr. Cheadle refers to in his journal: "Milton chose a fine hill to the left as his mountain, and I a still higher to the right....a long range of very rugged rocks, very high and snow-clad with green slopes, & bright pines half way up. Very fine indeed." (10 July 1863 entry from "The North-West Passage by Land", 1865, republished as "Cheadle's Journal of Trip Across Canada 1862-63" by M.G. Hurtig, 1971).
