2017 Map of Dewey

About this map

The Colorado River carves a dramatic path through this high desert region of Grand County, Utah, where it meets the Dolores River near the small settlement of Dewey. The landscape is defined by its massive river bottoms and sheer canyon walls, including the expansive Richardson Amphitheater and the distinctively named Mule Shoe bend. The iconic Dewey Bridge provides a critical crossing point for travelers moving through the canyons toward Professor Valley. High above the river corridor, the terrain transitions into complex plateaus and mesas like the Little Pinto Mesa and the Owl Draw Upland. This 2017 survey details a landscape where traditional transit routes, such as Gold Mine Rd and Fisher Tower Rd, follow the natural contours of the canyons, highlighting the area's isolation and its historical reliance on the river as the primary geographic anchor.
