About this map

Black Hawk sits at the heart of this 1972 survey, documenting a landscape shaped by early Colorado mining and rugged mountain geography. Evidence of the area's industrial past is visible in the numerous mine claims and geological features, including the Baltimore Mine, Hunky Dory Mine, and the Shamrock Mine. Further downstream, extensive Dredge Tailings along North Clear Creek and the Clear Creek Dredge Tailings reveal the scale of hydraulic and mechanical extraction that transformed these valley floors.

Modern recreational use is shown through the development of Golden Gate Canyon State Park, where campgrounds like Reverends Ridge Campground and picnic areas like Ralston Roost Picnic Area now occupy former timber and ranching land. The transition between the Roosevelt National Forest and Arapaho National Forest defines the western terrain, while peaks such as Tremont Mountain and Black Hawk Mountain provide the vertical backdrop for the deep gulches and creek networks.
