The County was established February 7, 1911 from the north and east parts of Bingham county. It was named for Captain B. L. E. Bonneville, of the U. S. Army, who explored the Snake River area in the 1830s. A settlement began at the site of the Eagle Rock ferry on the Snake River in 1864, this settlement was renamed Idaho Falls in 1891.
