Georgetown and Silver Plume sit at the northern heart of this survey, surrounded by the intense mining legacy of the Front Range. The landscape is a network of mid-century industrial activity, including the Lamartine Mine, Black Eagle Mine, and numerous portals like the Sunburst Tunnels and Queen City Tunnel. In the high peaks, the Inter Univ High Altitude Lab near Mt Evans and Summit Lake signifies the area's shift toward scientific research and alpine recreation.
