1950 Map of Juanita Arch

About this map

The Dolores River cuts a deep path through the high plateau country of western Colorado in this 1950 survey, which highlights a landscape shaped by both dramatic geology and early atomic-era resource extraction. While the towering sandstone formations like Tenderfoot Mesa and Sewemup Mesa dominate the topography, the map reveals the industrial activity of the period through the Maverick Mines and the Copper Rivet Mine. These remote sites are connected by the winding path of 141, the primary artery through this isolated canyon country. The intricate drainage systems of Salt Creek and Blue Creek illustrate the erosion patterns that created landmarks like the Juanita Arch. Of particular historical interest is the presence of the United States Atomic Energy Commission in the margin, signaling the area's importance during the uranium boom of the mid-twentieth century. Nearby, the enclosed basin of Sinbad Valley provides a distinct geographical contrast to the surrounding canyon walls and high mesas.
