"Blackfoot" is a name applied to several places in the area, including a mountain range and a small river. The name can be traced back to the summer of 1818 when a group of trappers and traders from the Hudson's Bay Company passed through. Earlier, in 1812, there had been some wildfires, and people who walked through the burned areas had their moccasins blackened. Although there were no actual Blackfoot people in the area, the traders referred to the people they met in the area as the Indians with the black feet, or the "Blackfoot Crowd", because of the blackened footwear. They went on to call the nearby stream the Blackfoot River. Blackfoot is the principal city of the Blackfoot, Idaho Micropolitan Statistical Area, which includes Bingham County.
