About this map

Louisville and the surrounding coal-mining settlements of Superior and Marshall define the landscape of this 1942 edition. Located along the Colorado and Southern railroad, the area is marked by an intricate network of irrigation systems like the Community Ditch and Church Ditch, which divert water across Davidson Mesa to sustain the local agricultural and municipal needs. The map captures the region's development just before post-war suburbanization, showing distinct community centers centered around institutions such as Sacred Heart Ch, Shamrock Sch, and Marshall Sch.

To the south, the terrain transitions into the high plateau of Rocky Flats, carved by Woman Creek and Walnut Creek. Significant water management features, including the Great Western Reservoir and Louisville Reservoir, highlight the critical role of hydraulic engineering in the Boulder and Jefferson County borderlands. For genealogists and local historians, the inclusion of the Superior Cem and small vanished localities like Marshallville provides essential data points for tracing early twentieth-century families.
