Rocky Bar, Idaho

Rocky Bar is a ghost town in Elmore County, Idaho, United States.

Rocky Bar was founded in December 1863 soon after gold was discovered along the nearby Feather River.

A ten-mile square area including Rocky Bar, covering much of the large basin in which it is located, is listed on the National Register of Historic Places as South Boise Historic Mining District.

Originally a placer mining camp, the South Boise area of Rocky Bar and Atlanta had a population of 560 by 1863.

Discovery of gold and silver lodes prompted the development of underground workings and 80 arastras by 1864.
