About this map

Glacier National Park reveals its dramatic verticality in this 2020 survey, where the Continental Divide National Scenic Trail winds along the spine of the Rockies. The map centers on the high-elevation divide separating Flathead and Glacier counties, showcasing a landscape defined by permanent ice and sharp summits. Notable landmarks like The Garden Wall and Crystal Point overlook a network of glacial water systems, including the Mokowanis River and McDonald Creek.

Tracing the path of the Going-to-the-Sun Road, the map illustrates the engineering required to navigate this terrain. Glacial remnants such as Chaney Glacier and the North Swiftcurrent Glacier are documented alongside significant alpine passes. From the depths of Sue Lake to the heights of Mt Merritt, the document provides a precise account of the park's contemporary topography, including named features like Atsina Falls and Granite Park.
