2017 Map of Ahern Pass

About this map

Glacier National Park dominates this high-altitude survey of the Northern Rockies, where the Continental Divide traces a jagged path across the Livingston Range. The map documents a landscape of dramatic verticality, defined by the towering arête of The Garden Wall and the precarious route of the Highline trail. Hydrological features are abundant, from the remote waters of Sue Lake and Helen Lake to the cascading Atsina Falls and Ipasha Falls. This 2017 study captures the status of several significant ice masses, including the Shepard Glacier, Ahern Glacier, and Old Sun Glacier, providing a benchmark for these receding features. Notable transit points like Ahern Pass and Swiftcurrent Pass mark the traditional crossings through this wilderness, while the engineering of the Going-to-the-Sun Road skirts the southern edge near Crystal Point.
