THE GROBIN DAVIS SITE: ARCHAEOGEOPHYSICS AND SETTLEMENT PATTERNS AT CADDO MOUND CENTERS IN SOUTHEASTERN OKLAHOMA

The Grobin Davis site (34MC253) is the best-preserved known prehistoric Caddo mound site in southeastern Oklahoma. The site, located along the Little River, consists of seven mounds arranged in a horseshoe configuration. Archaeological excavations at the site have been limited to a series of posthole tests and three 1-x-1-m units. Between November 2011 and February 2012, the Oklahoma Archeological Survey conducted geophysical survey of the bulk of the site, covering approximately 32,000 m² with a fluxgate gradiometer. This study provides important information about Caddo mound construction, settlement, and ceremonialism in southeastern Oklahoma and add to a growing body of literature on prehistoric Caddo community patterns.
