Description: Graham Cave is a Native American archaeological site near Mineola, Missouri in Montgomery County. The entrance of the sandstone cave forms a broad arch 120 feet (37 m) wide and 16 feet (5 m) high. Extending about 100 feet (30 m) into the hillside, the cave protects an historically important Pre-Columbian achaeological site from the ancient Dalton and Archaic period dating back to as early as 10,000 years ago. The cave was extensively excavated between 1949 and 1955 by the University of Missouri and the Missouri Archaeological Society. This image shows the edge of an excavation with layers dated more than 8800 years back. It partially exposes a circle of stones around a larger stone, considered to possibly be a council ring. Contrast adjustment is the only change made to this image after retrieval from the camera.
