1885 Map of Ashley

About this map

The Green River carves a dramatic path through the Uinta Mountains on this late-nineteenth-century reconnaissance survey. This era of exploration reveals the landscape before modern reclamation, highlighting topographic milestones like Flaming Gorge and the narrow passage of Horseshoe Canyon. To the south, the Uinta Valley opens into the Wonsits Valley, a region of significant early administrative activity. The presence of the White Rocks Uinta Indian Agency and the early settlement of Ashley marks the intersection of indigenous lands and expanding pioneer outposts. Researchers will find a world defined by its drainage basins, from the Henry River in the north to the confluence at Ouray, during a decade when the Utah Colorado Boundary Line was being definitively mapped through Browns Park.
