1885 Map of Ashley

About this map

The Green River carves a dramatic path through the northern Uintah Mountains in this reconnaissance-era study. The river enters from the north at the Utah Boundary Line, winding through Flaming Gorge and Horseshoe Canyon before cutting through the deeply incised Red Canyon. This period of surveying captures the early presence of the White Rocks (Uinta Indian Agency) and the settlement of Ashley, established before the modernization of the Uintah Basin. The map details the junction of the Green River and White River near Ouray, a key geographic point in the Wonsits Valley. High peaks like Marsh Peak and Leidy Peak overlook Summit Valley, while the eastern portion of the sheet documents the Utah Colorado Boundary Line near the remote ranching outpost of Browns Park.
