Washington State Park is a public recreation area covering 2,147 acres (869 ha) in Washington County in the central eastern part of the state of Missouri. It is located on Highway 21 about 14 miles (23 km) northeast of Potosi or 7 miles (11 km) southwest of De Soto on the eastern edge of the Ozarks. The state park is noted for its Native American rock carvings and for its finely crafted stonework from the 1930s.[3]
Stone carvings
The carvings, or petroglyphs, carved in fixed dolomite rock, are believed to have been made around 1000 to 1600 CE and to give clues to the lives of the prehistoric Native Americans who once inhabited this part of Missouri. It is also believed that the park served as ceremonial grounds for these Middle Mississippi people who were related to the builders of the Cahokia Mounds in Illinois.
Most of the carvings are of birds, arrows, footprints, turkey tracks, human figures, and various geometric shapes and patterns. The three petroglyph sites in the park are thought to be all that is left of a more extensive site. They make up almost 75 percent of the known petroglyphs in Missouri and contain over 350 symbols.[7]
