About this map

The Green River carves a dramatic path through northeastern Utah in this late-nineteenth-century survey, revealing a landscape defined by deep canyons and high peaks. The course of the river is punctuated by notable geological features like Flaming Gorge, Horseshoe Canyon, and Swallow Canyon before it meets the Yampa Plateau at Split Mt. Canyon. Settlement in this era is sparse, anchored by the Ashley community and the White Rocks (Uinta Indian Agency) to the west.

Southward, the Uinta River and White River converge near Ouray, flowing through the broad Won Sits Valley. This map captures the region when the Uinta Mountains remained largely inaccessible, with only a few named landmarks like Marsh Peak and Leidy Peak rising above the surrounding Summit Valley. The cartography by the King and Powell Surveys highlights the complex drainage systems that would eventually support the region's ranching and agricultural development.
