2023 Map of Island Park

About this map

Dinosaur National Monument occupies the southern portion of this landscape, where the Green River carves through a complex of riverine meadows and isolated landforms. Named islands such as Bobby Island, Hog Island, and Ford Island punctuate the river's path through Island Park, a notable broad valley between high ridges. The terrain transitions from the high elevations of Diamond Mtn and Boone Ridge in the north down to the riparian flats of Upper Meadow and Lower Meadow. Local water sources like McKee Spring and Boone Spring supported early access to this remote stretch of Uintah County, while a network of primitive routes including Boone Ridge Rd and the Ruple to Ely Trl trace the topographic benches and draws. The map illustrates a landscape defined by significant erosion, with deep cuts like Wolf Hollow and Limekiln Draw feeding toward the river valley.
