Bon Homme County, Administrative county in South Dakota, United States
Bon Homme County spans 582 square miles along the Missouri River, featuring rolling hills that slope toward the river valley for agricultural purposes.
The county, established in 1862, takes its name from Bon Homme Island, which Lewis and Clark documented during their 1804 expedition through the region.
The county population reflects strong German, Czech, and Dutch heritage, with these ancestral groups comprising over 80 percent of resident backgrounds.
The county seat of Tyndall connects to major regional destinations through South Dakota Highways 25, 37, 46, 50, and 52.
In 1860, settlers constructed Dakota Territory's first schoolhouse, which opened with ten students under the instruction of Emma Bradford.
