1954 Map of Canyon of Lodore South

About this map

Green River and Yampa River converge in this mid-century survey of the high desert of Moffat County, dominated by the deep incisions of the Canyon of Lodore. This area within Dinosaur National Monument is defined by dramatic geological features such as the towering Steamboat Rock and the treacherous rapids of Hells Half Mile and Triplet Falls. Remote human activity is recorded through scattered landmarks like Massey Cabin and Buffham Place, which suggest the sparse ranching and exploration history of the basin. The landscape is a network of ridges and draws, including Iron Mine Ridge and Limestone Ridge, while freshwater sources such as Chokecherry Spring and Warm Springs provide vital points in an otherwise arid terrain. The map also captures local lore and geography at Echo Park (Pats Hole) and the iconic Jenny Lind Rock.
