History

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.[3][4]

The Oregon Trail crossed the Snake River in Elmore County, at Three Island Crossing near Glenns Ferry. 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.[5]

Construction of what would become Mountain Home Air Force Base was begun in October 1942, 12 miles (19 km) southwest of Mountain Home. The base officially opened in August 1943 as a training base for bombers, and was an operational base under SAC through 1965. It became a fighter base in 1966 under TAC, now the Air Combat Command.

Anderson Ranch Dam is east of Mountain Home on the South Fork of the Boise River. At the time of its completion in 1950, it was the world's highest earthfill dam.[6]
