1955 Map of Tortuga

USGS Topo · Published 1955

About this map

The Chocolate Mountains and the arid expanse of the East Mesa dominate this mid-century survey of Imperial County. The landscape is a study in survival and infrastructure, defined by the Coachella Canal cutting across the desert floor and the heavy presence of the Chocolate Mountain Aerial Gunnery Range, which occupies the northern reaches. Water, or the lack thereof, is the central theme, evidenced by several marked desert sources such as Barth Well and Melson Well.
