A unique petroglyph panel in southeastern Missouri appears to be a cartographic depiction of the Mississippi River, a series of Middle Mississippian places, and, perhaps, social or political identities (ca. A.D. 1200-1400). The panel, part of the Commerce Quarry and Petroglyph site, sits adjacent to a millennia-old Mississippi River crossing on a prominent natural feature which also was a likely raw-material source for the production of quartzite chunkey stones. The Commerce map is the oldest known cartographic representation in eastern North America, marking a significant location in regional space and Mississippian cultural history.
