1959 Map of Two Ocean Pass

About this map

Two Ocean Pass serves as a remarkable hydrological landmark within Teton National Forest, where North American waters split toward two different oceans. This 1959 field-checked survey captures the intricate drainage patterns of the Continental Divide, specifically where Atlantic Creek and Pacific Creek emerge from the same marshy meadow. The landscape is defined by the headwaters of the Yellowstone River and the Snake River, connected by an extensive network of primitive paths including the Thorofare Trail and various unnamed pack trails. Evidence of early wilderness management is visible at the Thorofare Ranger Station and Hawks Rest Patrol Cabin. The map highlights the intersection of several county boundaries, including Teton, Park, and Fremont, while documenting the massive Two Ocean Plateau and prominent heights like Hawks Rest and Yellowstone Point.
