1968 Map of Mount Jackson

About this map

The Continental Divide carves a path through the high peaks of Glacier National Park, serving as the spine for a landscape dominated by massive ice fields and steep drainages. In the late 1960s, this area of the park remained defined by active glacial systems including Sperry Glacier, Jackson Glacier, and the extensive Blackfoot Glacier. The map details the intricate relationship between these glaciers and the alpine hydrology they feed, from Gunsight Lake at the head of the St Mary River to the southern waters of Harrison Lake. The transition from the high-altitude Crevasses near Mount Jackson to the lower valley floor of Nyack Creek illustrates the stark verticality of the terrain. Human presence is marked primarily by rugged travel routes like the Gunsight Trail and a isolated Shelter Cabin, emphasizing the wilderness character of the Flathead and Glacier county border during this era.
