Placerville and its surrounding Boise Basin mining district are defined by a network of steep gulches and creek drainages within the Boise National Forest. The map documents a cluster of settlements including Centerville, New Centerville, and Quartzburg, connected by forest service roads and local routes like California Gulch Rd. High points such as Alder Creek Summit and Mineral Mtn overlook a landscape carved by Grimes Cr and Granite Cr. The layout of the drainages, from Slaughterhouse Gulch to Treasure Gulch, suggests the intense historical hydraulic and placer mining activities that once dominated this region of Boise County. Modern utility is seen at the Treasure Gulch Airport, while numerous flats and ravines like Huckleberry Flat and Little Crooked Ravine provide specific geographic markers for local history and land use.
