1885 Map of Uinta

About this map

The Uinta Mountains dominate this high-altitude reconnaissance, representing the results of early surveying by the King and Powell expeditions. This landscape is defined by its massive plateaus and towering summits, including Gilbert Peak, Emmons Peak, and Mt Agassiz, which separate the headwaters of several major drainages. To the north, the Bear River flows toward the Great Salt Lake basin, while the southern slopes feed the massive Uinta Valley through a network of waterways including the Duchesne River, Uinta River, and Lake Fork Creek. The geography reveals a primitive wilderness before modern development, characterized by the high elevations of the Rhodes Plateau and Concrete Plateau. The presence of the Utah Boundary Line at the northern edge marks the territorial limits during this era of western expansion and geological discovery.
