1959 Map of Two Ocean Pass

USGS Topo · Published 1960

About this map

Two Ocean Pass serves as a geographic centerpiece for this high-altitude wilderness, where the Continental Divide dictates the drainage of the American West. The map documents the intricate hydrology of the upper Yellowstone River and Thorofare River basins within Yellowstone National Park and the adjacent Teton National Forest. Notable landmarks such as the Thorofare Ranger Station and Hawks Rest Patrol Cabin mark remote outposts in a landscape dominated by peaks and plateaus. The drainage pattern is unique, particularly at the pass where waters part toward the Atlantic and Pacific oceans via Atlantic Creek and Pacific Creek. A network of historic paths, including the Continental Divide Trail and the Atlantic-Pacific Trail, provides the primary means of traversal through this roadless territory as it was surveyed in the late 1950s.
