The mining camps of Georgetown and Silver Plume anchor this 1957 survey, illustrating a landscape deeply marked by nineteenth-century silver extraction. The canyon floor is a complex network of industrial heritage, featuring the Old Railroad Grade and the engineering of the Georgetown Loop. The surrounding peaks are densely peppered with adits and shafts, from the Seven Thirty Mine high on the northern slopes to the Mendota Mine and Terrible Mine near the valley bottom.
