About this map

The Colorado River carves a deep path through this section of Grand County, joined here by its tributary, the Dolores River. The small settlement of Dewey sits near the river junction, marked by the historic crossing at Dewey Bridge. This landscape is defined by massive mesas and tiered sandstone benches, including Hotel Mesa and Roberts Mesa, which overlook expansive river flats like McGraw Bottom and Ninemile Bottom.

Evidence of early exploration and movement is visible through the winding course of Highway 128 and the presence of a Gold Mine near the southern boundary. Distinctive natural landmarks such as Arrowhead Arch and the expansive Richardson Amphitheater showcase the unique erosion patterns of Professor Valley. Researchers can trace the layout of various river bottoms and springs, including Buck Spring and Dewey Spring, which provided critical water sources in this arid environment.
