1957 Map of Hot Sulphur Springs

About this map

Hot Sulphur Springs serves as the focal point of this mid-century survey, situated where the Colorado River carves through the dramatic Byers Canyon. The landscape transition from the high peaks of the Arapaho National Forest to the river valley is marked by the presence of the Denver and Rio Grande Western railroad, which follows the river's course past Parshall. This period of mapping records the area just as the Williams Fork Reservoir expansion was planned, noted by the blue hatching indicating future inundation zones.
