About this map

Logan Pass serves as the focal point for this survey of the Continental Divide in Glacier National Park. The dramatic alpine topography is defined by the winding route of the Going-to-the-Sun Road, which traverses the landscape near landmarks like the Weeping Wall and the Triple Arches. The map documents a high-altitude environment of permanent ice and snow, including Grinnell Glacier, Siyeh Glacier, and the Sexton Glacier.

Glacial action has carved sharp arêtes and deep basins, such as The Garden Wall and the Hanging Gardens. Water features are abundant, from the alpine depths of Hidden Lake and Gunsight Lake to the dramatic vertical drops of Morning Eagle Falls and Bird Woman Falls. This record illustrates the complex drainage patterns where the Saint Mary River and Logan Cr originate from these ancient ice fields.
