The Green River carves a winding path through the northern reaches of the Uinta Mountains, defining the landscape of this high-altitude border region. This 2023 survey illustrates the rugged transition where the river flows through Swallow Canyon before opening into the broad valley of Browns Park. The map documents the extensive Browns Park National Wildlife Refuge, which spans the river corridor across the Utah and Colorado state line.
