Black Hawk and Central City anchor this 2016 survey of the high-elevation terrain where Gilpin, Clear Creek, and Jefferson counties meet. The map traces the dense network of drainage and terrain features that defined the early mining era, from Gregory Gulch to Russell Gulch, highlighting how the modern footprint of these towns remains tied to the steep slopes of Gregory Hill and Signal Hill. This area is a patchwork of public and private lands, with significant portions managed as part of the Roosevelt National Forest and Arapaho National Forest.
