Chalk Level (also spelled Chalklevel) is an unincorporated community in St. Clair County, in the U.S. state of Missouri.[1]
A post office called Chalk Level was established in 1848, and remained in operation until 1914.[2] The community most likely was so named on account of the chalky character of the soil at the flat town site.[3] It is also rumored that the city got its name from its "level headed" residents who could "chalk" it down. Another story pointed to a local carpenter who spent a lot of time chalking and leveling his buildings.[4]
