Idaho County is a county in Idaho, United States, the largest county in the state by land area and the only one that touches both Oregon and Montana. It had a population of 16,541 at the 2020 census and covers 8,477 square miles (21,960 km2) of land, centred near 45°51′N 115°28′W.<\/p>\n
Grangeville is the county seat, and its postal code is 83530. The county has 7 incorporated cities and dozens of small unincorporated communities, ghost towns and former mining camps scattered across the Salmon River and Clearwater River backcountry. Because the Salmon River splits the county, the northern half runs on Pacific time and the southern half on Mountain time.<\/p>\n
Idaho County has 7 incorporated cities and roughly 70 unincorporated communities, most of them former gold-mining camps or ranger stations in the Nez Perce–Clearwater and Payette National Forests. “CDP” marks a Census Bureau-defined place with no city government; “Unincorp.” marks a named locality, ghost town or historic site with no formal boundary.<\/p>\n

Elk City and Dixie sit far enough apart to share the 83525 ZIP with several smaller camps between them.<\/p>\n ZIP Codes<\/h2>\nMost of the backcountry mining camps and ranger stations — Warren, Burgdorf, Orogrande, Florence, Mount Idaho and the rest — have no post office of their own and are served by the nearest of the ZIPs above.<\/p>\n Geography<\/h2>\nIdaho County is Idaho’s largest county by land area, stretching from the wheat country around Grangeville and Cottonwood on the Camas Prairie down through the Salmon River canyon — one of the deepest gorges in North America — into the roadless Frank Church–River of No Return and Selway-Bitterroot wilderness areas. The Nez Perce–Clearwater and Payette national forests cover most of the county, and its northwest corner takes in part of the Nez Perce Indian Reservation. The county is unusual for reaching two other states: its eastern edge touches Montana and its western edge touches Oregon.<\/p>\n |
