2015 Map of Observation Peak

About this map

Observation Peak stands as the central landmark within the Snake River Range, marking a high point where the high-altitude topography of the Teton National Forest meets the Targhee National Forest. The landscape is defined by a complex network of drainage basins and ridges, with Lake Basin providing a rare level catchment area beneath the surrounding peaks. Access across this steep terrain is primarily via historical routes such as the Divide Trail and the Dog Creek Headwaters Trail, which navigate the sharp elevations between North Indian Creek Pass and Red Pass. The hydrology of the area is intricate, with headwaters for S Fork Fall Creek and Wolf Cr carving deep features like Big Basin Canyon and Deadhorse Canyon. This survey captures the wilderness boundary between Teton and Lincoln counties, emphasizing the primitive trail systems that remain the primary means of traversal.
