2010 Map of Dewey

About this map

The Colorado River carves a deep path through Grand County, serving as the central artery for this remote high-desert landscape. Near the confluence with the Dolores River, the river creates distinctive alluvial flats such as Hittle Bottom, Ninemile Bottom, and Roberts Bottom. The settlement at Dewey and the nearby Dewey Bridge mark a critical crossing point in a region dominated by sheer topographical barriers like the Richardson Amphitheater and Hotel Mesa. Local land use is characterized by isolated outposts like Gordon Ranch and Cato Ranch, which occupy the few accessible areas between the steep walls of Yellow Jacket Canyon and Waring Canyon. The presence of Gold Mine Rd and various natural springs, including Buck Spring, indicates a long history of resource seeking and ranching in the Professor Valley area.
