1965 Map of Eldorado Springs

About this map

Eldorado Springs and the southern reaches of Boulder anchor this mid-1960s survey of the Front Range. The landscape is defined by the complex engineering of the Denver and Rio Grande Western railroad as it winds through the foothills, utilizing numerous tunnels to navigate the terrain between Plainview and Crescent Village. The map highlights the intersection of academic and scientific growth with the natural environment, featuring the National Bureau of Standards and the Institutes for Environmental Research on the city's edge. Water management is a dominant theme, evidenced by the sprawling Gross Reservoir and the Kossler Lake system. For local historians, the sheet preserves the location of scattered mountain settlements like Copperdale and Magnolia, along with essential community fixtures such as the Chapel in the Hills and the Green Mountain Memorial Park Cemetery.
