Welcome to Elmore County

Elmore County was established February 7, 1889, with its county seat at Rocky Bar. It is named after the Ida Elmore mines, the area’s greatest silver and gold producer of the 1860s, located near Silver City in Owyhee County.

A station on the overland stage route, originally named Rattlesnake, was moved west to the railroad line and became Mountain Home. On February 4, 1891, the county seat was moved to Mountain Home.

Burn Ban in effect from June 25 through October 19. Conditions permitting in October.
