About this map

Glacier National Park reveals its high-altitude ice fields and sharp topographic relief in this late-1960s survey along the Continental Divide. Centered on the towering peak of Mount Jackson, the landscape is defined by massive glacial formations including Jackson Glacier, Blackfoot Glacier, and the Harrison Glacier. The presence of numerous crevasses and falls throughout the quadrangle highlights the active nature of this alpine environment during the era of the field check.

Evidence of wilderness navigation and mountaineering history is found in the Gunsight Pass Trail leading to the Gunsight Shelter Cabin near the shores of Gunsight Lake. The drainage patterns are clearly delineated, showing the origins of the St Mary River and the southward flow of Nyack Creek. Straddling the border between Glacier and Flathead counties, the map documents the critical water sources and high peaks such as Mount Logan and Mount Thompson.
