2013 Map of Owyhee

About this map

The Idaho State Correctional Institution and the State Penitentiary anchor the northern landscape of this Boise-area quadrangle. Located south of the capital in Ada County, the area transitions from industrial and institutional footprints into a network of desert drainage systems and ranching infrastructure. Arid waterways like Tenmile Cr, Indian Cr, and Bryans Run score the terrain, leading toward Blacks Cr Reservoir. The settlement at Owyhee and the district of Pleasant Valley are defined by long, straight thoroughfares such as Kuna Mora Rd and Pleasant Valley Rd, illustrating the systematic public land survey system that carved this high-desert region into functional grids. Recreational and specialized land use is evident at the Blacks Creek Rifle Range, while various unimproved routes like Airstrip Access suggest the logistical needs of this isolated reach.
