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.
Another story pointed to a local carpenter who spent a lot of time chalking and leveling his buildings.
