The gold mining legacy of Gilpin County is on full display in this 1942 survey, centered on the high-altitude hub of Central City. The map reveals a densely concentrated landscape of extractive industry, from the massive Glory Hole and Chain O Mine near the city center to the Pittsburg Mine in Lake Gulch. The steep terrain between Maryland Mountain and Seaton Mountain is etched with specialized infrastructure, including an Abandoned Flume and the Fall River Power Plant, illustrating how water and power were harnessed for large-scale mountain operations.
