2020 Map of Island Park

About this map

Dinosaur National Monument encompasses the southeastern portion of this landscape, where the Green River carves through a series of islands including Bobby Island, Hog Island, and Ford Island. The terrain is defined by dramatic elevation changes from the high plateau of Diamond Mtn and Boone Ridge down to the riparian flats of Island Park. This area serves as a critical junction of historical travel and resource access, evidenced by the Ruple To Ely Trail and the placement of vital water sources like Boone Spring, Cottonwood Spring, and McKee Spring. The map documents a rugged drainage system where Diamond Gulch and Limekiln Draw funnel toward the river basin. From the sweeping McKee Bench to the quiet reaches of Rainbow Park, the geography illustrates the complex erosional patterns typical of the Uintah County backcountry.
