During the construction of Lewisville Dam in 1950, aboriginal artifacts were unearthed at this site, and archeologists carried out several excavations from 1952 to 1957 before the waters of Garza-Little Elm Reservoir covered it. Those excavations uncovered 21 hearths, vegetable matter, animal bone fragments, and lignite used for fuel. Scientific radiocarbon dating indicates that the organic material is approximately 12,000 years old, and the discoveries are similar in age and content to findings at the Clovis site in New Mexico.
