About this map

Yellowstone National Park dominates this landscape, specifically the remote southern reaches of Yellowstone Lake. The geography is defined by the deep waters of the South Arm and Southeast Arm, separated by the high ground of The Promontory. The map details a wild, non-motorized landscape where human presence is limited to a network of back-country paths. Notable routes include the Two Ocean Plateau Trl, the Tri Creek Trl, and the Tri Creek-Two Ocean Cutoff Trl.

Smaller water bodies and landforms provide specific points of interest for navigation and study, such as Alder Lake tucked inland from the primary shoreline and Peale Island located within the lake's expanse. To the west, the steep elevation of Chicken Ridge and Channel Mtn overlook the water, while Chipmunk Cr drains the southern high country. This document preserves the primitive character of the park's interior as it remained in the early 21st century.
