1998 Map of Placerville

About this map

Placerville and its surrounding mining districts remain the focus of this late-20th-century topographic record, which documents a landscape heavily shaped by generations of extraction. The settlement patterns reflect a legacy of prospecting, with clusters of activity near Centerville and New Centerville along the lower reaches of Grimes Creek. The terrain is deeply incised by named gulches such as Slaughterhouse Gulch and Illinois Gulch, many of which show evidence of historical surface work. Significant industrial traces appear throughout the quadrangle, notably the extensive Tailings deposits at Mud Flat and numerous specific operations like the Leary Placer Mine and Gold Hill Mine. For the local historian, the map preserves the exact locations of isolated landmarks like Brassey Ranch and the high point at Alder Creek Summit, alongside various Prospects that point to the region's enduring identity as a mineral-rich corridor within the Boise County highlands.
