2021 Map of Sage Creek Basin

About this map

Flaming Gorge Reservoir dominates the western edge of this Sweetwater County landscape, where the waters of the Green River system meet the high desert plateau. The terrain is defined by dramatic vertical relief, notably at North Chimney Rock and South Chimney Rock, which serve as prominent landmarks for those navigating the eastern shores. A significant portion of the western territory is managed as part of the Ashley National Forest, while the central expanse opens into the broad Sage Creek Basin. Remote water sources like Greasewood Spring in Greasewood Draw suggest the traditional patterns of range management and wildlife movement in this arid environment. The road network, including the Flaming Gorge Rd, follows the natural contours of the canyons and basins, providing access to the recreationally and geologically significant Firehole Canyon.
