2020 Map of Placerville

About this map

Placerville stands as a central point in this Boise County landscape, situated within the northern reaches of the Boise National Forest. The map documents a rugged interior defined by the Boise Basin, where narrow gulches and steep ridgelines dictated the development of early settlements. From the heights of Mineral Mtn and Alder Creek Summit to the creek-side locations of Centerville and New Centerville, the placement of these towns reflects the legacy of the region's historic mining activity. Distinctive local names like Slab Cabin Gulch, Slaughterhouse Gulch, and Confederate Gulch speak to the specific character of the 19th-century boom years that shaped this terrain. Transportation remains tied to the land's contours, with the Grimes Pass Rd and Ida City-Horseshoe Bend road providing primary access through the mountain passes and along Granite Cr.
