Yellowhead Lake is in Robson Provincial Park. As is the south/east face of Yellowhead Mountain. However a line connecting the tops of the three main peaks, from left to right, Leather Peak, Lucerne Peak and Tete Roche is the border between Robson Provincial Park and Jasper National Park. Also the border between British Columbia and Alberta.

As this image was taken from the Robson side of the border I have placed it in the Robson Gallery.
