Elmore County was established February 7, 1889 with its county seat at Rocky Bar. The county was named for the Ida Elmore mines, the area's greatest silver and gold producer of the 1860's. The Oregon Trail crossed the Snake River at Three Island Crossing near Glenns Ferry. A station on the overland stage route, originally named Rattlesnake, was moved to the railroad line and became Mountain Home. 4 February 1891 the county seat was moved to Mountain Home. Communities in Elmore County include: Atlanta, Featherville, Glenns Ferry, Hammett, King Hill, Mountain Home, and Rocky Bar. Elmore county is home to three of Idaho's major reservoirs; Lucky Peak, Anderson Ranch, and Arrowrock and is also home to Idaho's only major military installation, Mountain Home Air Force Base.
Elmore County is surrounded by Boise County on the north; Blaine County, Camas County, Gooding County and Twin Falls County on the east; Owyhee County on the south; and Ada County on the west. Elmore County was formed from Alturas County.
| Did You Know... Idaho has a long roster of tough pioneers, but one of the toughest was “Pegleg” Annie Morrow, of Elmore County (pop 29,130). One winter day in 1896 while she was walking across Bald Mountain with her friend Dutch Em, a fierce blizzard blew up. When a search party found the pair, Morrow was half frozen and her friend was dead. A doctor amputated Morrow’s frozen feet. Morrow later became a mother and successful businesswoman. She died in 1934 and was buried in Boise’s Morris Hill Cemetery.Idaho Tidbits & Trivia |
