1990 Map of Santa Ana Pueblo

Transport and utility history is etched into the terrain via an Old Railroad Grade that skirts the southern shore of the reservoir and river. Further markers of mid-century industrial activity and modern communication appear through scattered labels for a Gravel Pit, Prospect, and a Communication Tower. The map provides a detailed view of the water control systems of the late 20th century, including multiple pumping and gaging stations necessary for managing the river's flow through the high desert canyon.
