Elmore County

Elmore County is an administrative county in southern Idaho encompassing diverse terrain with mountains, rivers, and open spaces. Mountain Home serves as the county seat and administrative hub for the region.

The county was established in 1889 as an administrative division in Idaho's growth period. The arrival of the military base in the 20th century significantly changed the area's development and population growth.

The Mountain Home Air Force Base shapes local life, bringing military families into the community and influencing local businesses and schools. Many residents have connections to the base, making military service part of the town's everyday fabric.

Visitors can access government services at offices in Mountain Home, including property tax records and vehicle registration. Main administrative services are available during business hours at the county seat.

Glenns Ferry, a section within the county, has a branch motor vehicle office that opens on specific days for local service. This smaller facility helps residents in more remote areas who cannot always travel to the county seat.
