About this map

The international border between the United States and Canada bisects this mountainous landscape, where the northern edge of Glacier National Park meets Waterton Lakes National Park. The terrain is defined by the massive Porcupine Ridge and high peaks like Campbell Mountain and Shaheeya Peak. Water dominates the eastern half of the sheet, where Waterton Lake fills the deep Waterton Valley, fed by the Waterton River and multiple cascades including Rainbow Falls.

Remote outposts and park infrastructure provide evidence of early 20th-century wilderness management, including the Waterton Ranger Sta, a Patrol Cabin, and the Boundary Warden Cabin. High-elevation lakes such as Carcajou Lake and Lake Frances are connected by a network of footpaths like the Boundary Trail and the Olson Boulder Pass Trail, which served as the primary routes for rangers and early travelers through the high passes.
