1985 Map of Dewey

About this map

The Colorado River and Dolores River converge in this high-desert landscape, creating a complex network of river bottoms and steep canyon walls. Small settlements like Dewey and Richardson are situated near these vital water sources, with Dewey notably featuring a Gaging Station to monitor the river's flow. The terrain is characterized by massive formations such as the Dome Plateau and Hotel Mesa, while landmarks like the Natural Arch and the Richardson Amphitheater highlight the area's geological diversity. The map reveals how early 1980s navigation and settlement were dictated by the deep incisions of Bull Canyon and Yellow Jacket Canyon, forcing transit through specific breaks like Professor Valley and across several named bottoms, including Ninemile Bottom and Hittle Bottom.
