1985 Map of Dewey

About this map

Colorado River and Dolores River meet in this canyon-carved landscape of Grand County, Utah. The settlement of Dewey sits near the confluence, supported by water sources like Dewey Spring and served by a Gaging Station. The geography is defined by deep incisions through the Dome Plateau and broad alluvial flats known locally as bottoms, including Ninetime Bottom, Hotel Bottom, and Roberts Bottom. To the south, the terrain drops into the striking Richardson Amphitheater and opens into Professor Valley. These named flats along the river loops suggest a history of seasonal grazing and early river-access points in an otherwise formidable terrain of mesas like Hotel Mesa and Little Pinto Mesa. A single adit and scattered springs like Couskin Spring provide evidence of early prospecting and vital water management in the arid West.
