Harco

(Illinois)

Harco is an unincorporated community in Saline County, Illinois, United States. The Harrisburg Colliery Coal Company Mine was sunk in November 1916, in the center of section 27, township 8, range 5, Saline County, Illinois, and the town of Harco soon grew up around it. The name of the town is derived from the first three letters of Harrisburg and the first two letters of Colliery, spelling “Harco.”
