About this map

Mammoth Cave and the surrounding karst topography of the Pennyroyal Plateau dominate this early 1920s survey. The landscape is defined by its subterranean complexity and surface sinkholes, including Double Sinks, Cedar Sink, and Hunts Sink. The Green River meanders sharply through the north, featuring notable landmarks like Turnhole Bend and Three Sisters Island.

A dense network of rural infrastructure supports the agricultural and early tourism economy of the era. Numerous country schools such as Maple Spring School and Silent Grove School are scattered across the ridges, while the Louisville and Nashville railroad corridor anchors southern settlements like Smiths Grove and Glasgow Junction. The map also records the location of prominent mineral springs and caves, including Colossal Cave and Chalybeate Springs, reflecting the region's developing identity as a geological destination.
