1885 Map of Ashley

About this map

White River and the Green River converge in the southern reaches of this Northeastern Utah territory, anchoring a landscape where river travel and mountain passes dictated early settlement. The White Rocks (Uinta Indian Agency) stands as a primary administrative and social hub near the western border, while the small settlement of Ashley marks an early presence in the central valley. The topography is dominated by the massive Uinta Mountains, featuring prominent summits like Marsh Peak and Leidy Peak. The map documents the dramatic path of the Green River as it carves through Flaming Gorge, Horseshoe Canyon, and Red Canyon before entering the broad Browns Park area near the Utah Colorado Boundary Line. This reconnaissance data, derived from the foundational King and Powell surveys, illustrates the region prior to widespread modern development, emphasizing the natural corridors of Summit Valley and the Wonsits Valley.
