1959 Map of Mount Hancock

About this map

Yellowstone National Park meets the Teton National Forest at this high-altitude junction along the Continental Divide. The terrain is defined by massive formations such as Big Game Ridge and the Two Ocean Plateau, where the famous Two Ocean Passage marks a rare hydrological point where waters can flow toward either the Atlantic or Pacific oceans. The mapping, based on 1954 aerial photography and 1959 field checks, documents a network of backcountry infrastructure essential for wilderness management. Remote outposts like the Harebell Creek Patrol Cabin, Fox Creek Patrol Cabin, and Gravel Creek Patrol Cabin are connected by established routes like the Heart River Trail and Snake River Trail. These cabins and trails supported park rangers and foresters in a region dominated by peaks like Mount Hancock and Barlow Peak.
