1942 Map of Nederland

About this map

The town of Nederland serves as a hub for this high-altitude landscape within the Roosevelt National Forest, where the transition from mining to early water management is clearly visible. Surveyed during the early 1940s, the map documents a region heavily influenced by extraction and the expansion of the Denver Salt Lake railroad. Hard-rock mining legacy is evident through the Bluebird Mine, Conger Mine, and Illinois Mine, while timber operations are marked by the Zarlengo Saw Mill near Park Lake. The presence of the Barker Reservoir and Lakewood Reservoir indicates the growing importance of the area for water storage serving the Front Range. Smaller settlements like Caribou, Eldora, and Rollinsville are connected by roads and rail through steep terrain, including the narrow corridor of South Boulder Creek.
