Mining and high-country ranching operations define the landscape along the Garfield and Pitkin County line during the early 1960s. The coal industry's footprint is evident through the presence of the Marion Mine, Union Mine, and industrial Coke Ovens located near Marion Gulch. These operations are supported by a network of infrastructure including a Pipeline and several Air Tunnels associated with the Thompson Creek Mine.
