About this map

Middle Boulder Creek and South Boulder Creek dominate this 1970s landscape, providing the drainage for a region defined by its intensive mining history and water infrastructure. The map details the operations of the Ruby Mine, Orange Blossom Mine, and Mammoth Mine, among others, situated within the Roosevelt National Forest. Significant engineering is visible through the presence of the Aqueduct system and Barker Reservoir, while the Denver Rio Grande and Western railroad winds through the canyons.

Small settlements such as Rollinsville, Pinecliffe, and Lincoln Hills are shown along the rail line, providing a record of mid-century community placement in the front range. To the south, Golden Gate Canyon State Park and the Starr Peak Lookout Tower offer evidence of the region's managed wilderness and fire lookout network. The complex network of gulches like Lump Gulch and Baker Gulch suggests a landscape deeply worked for mineral extraction since the initial mining booms.
