About this map

Two Ocean Pass serves as the focal point of this high-country survey, where the hydrologic curiosity of a stream splitting toward two different oceans is documented across the Continental Divide. The landscape is dominated by the upper reaches of the Yellowstone River and its confluence with Thorofare Creek near the Bridger Lake wetland complex. This area, shared between Yellowstone National Park and Teton National Forest, shows a remote wilderness managed through scattered outposts such as the Hawks Rest Patrol Cabin and the Thorofare Ranger Station.

Transport through this roadless terrain is defined by an extensive network of pack routes, including the Thorofare Trail and the Atlantic-Pacific Trail. These paths follow the natural corridors of the Snake River and numerous drainages like Mink Creek and Falcon Creek. The survey identifies the tiny settlement of Daniels and the high elevation Phelps Pass, illustrating the logistical challenges and isolation of the Teton and Park County borderlands in the late 1950s.
