1968 Map of Ahern Pass

About this map

Glacier National Park reveals its high-altitude drainage systems and massive ice fields in this late 1960s survey. The Continental Divide snake-like through the center of the sheet, separating the Pacific and Atlantic watersheds. Hikers and researchers can trace the Highline Trail as it traverses the western face of The Garden Wall, a dramatic arête that looms over the headwaters of McDonald Creek. Notable backcountry structures including the Granite Park Chalet and the Fifty Mtn Shelter Cabin serve as key landmarks for mountaineering history. The map documents numerous receding ice masses like the Swiftcurrent Glacier and Ahern Glacier, alongside named falls such as Atsina Falls and Ipasha Falls. At the southern edge, the engineering of the Going-To-The-Sun Road is visible at The Loop, marking the transition from deep valley floor to the high peaks of the Livingston Range.
