About this map

The Green River carves a serpentine path through this 2020 landscape in Uintah County, creating a series of distinct river bottoms that define the local topography. This portion of the Uinta Basin is dominated by the sprawling Ouray National Wildlife Refuge, which protects the vital riparian corridor and wetlands of the river valley. The map details the intricate bends of the waterway, including the prominent Horseshoe Bend and the broad floodplains of Leota Bottom and Brennan Bottom.

Isolated roads like Baeser Wash Rd and Wonsits Valley Rd navigate the high desert terrain and provide access to the river's edge. The land is marked by significant geographic depressions and flats, from Brennan Basin in the center to Wonsits Valley in the south. This modern survey illustrates how the natural hydrology of the Green River continues to shape the character of the region, maintaining a mosaic of open water and dry flats such as Johnson Bottom and Wyasket Bottom.
