1959 Map of Two Ocean Pass

About this map

Two Ocean Pass serves as the focal point of this hydrologically significant region, where the Continental Divide separates the headwaters of the Atlantic and Pacific watersheds. The map documents the wilderness character of the area where the Yellowstone River and Thorofare River converge near Bridger Lake. This 1959 survey reveals an extensive network of pack trails, including the Thorofare Trail and the Atlantic-Pacific Trail, which provided the primary means of transit through Yellowstone National Park and the Teton National Forest. Administrative presence in this remote backcountry is noted by the Thorofare Ranger Station and the Hawks Rest Patrol Cabin near the prominent landmark of Hawks Rest. The landscape is defined by massive geographic features like the Two Ocean Plateau and the Cliff Escarpment, underscoring the area's isolation before modern developments reached deeper into the Wyoming interior.
