Central City and Black Hawk anchor this high-altitude landscape, illustrating the enduring footprint of Colorado's historic mining district. The map captures the dense network of gulches and ridges that shaped early development, including Gregory Gulch and Chase Gulch, where gold was first discovered in the region. To the north, the small settlement of Dory Hill is home to the Gilpin County Courthouse and the Dory Hill Cem, while Idaho Springs sits along the southern edge near Clear Creek.
