Williamson, Conover, and Cactus Hill: the significant Clovis sites of the Nottoway River drainage, southeastern Virginia by Joseph M. McAvoy Abstract: Three Clovis sites in the Nottoway River drainage of southeastern Virginia are significant, related, and together define the local Clovis landscape. The Williamson site located in the Fall Zone of the Piedmont has been know for over 50 years as a large chert quarry and residential base camp. The site was investigated further in 1999 with findings relating to previously unknown activities. The Conover Clovis site is 11.6 km to the southeast of Williamson, and it is a smaller base camp strategically situated upon an upland Coastal Plain drainage divide. Five artifact clusters have been identified, which consist primarily of Williamson chert. Cactus Hill is a hunting camp and quartzite cobble source adjacent to the Nottoway River near low-ground swamps of the Coastal Plain, 19 km southeast of Williamson. This culturally stratified sand dune contains in situ, datable Clovis-age features also containing Williamson chert artifacts. http://nottowayriversurvey.com/ Joseph M. McAvoy Joseph M. McAvoy, and his wife Lynn, founded Nottoway River Survey, a research group in Sandston, Virginia, in 1979. The group specializes in Paleoindian studies in southeastern Virginia. Mr. McAvoy has worked for more than 12 years as principal investigator and manager for the NRS Cactus Hill archaeological project under grants from the Virginia Department of Historic Resources and the National Geographic Society, and he has recently completed an evaluation of the Williamson Clovis site for the state of Virginia. His special interests are Clovis settlement patterns in Virginia, pre-Clovis sites on the Nottoway and Chowan Rivers of Virginia and North Carolina, and Clovis-age quarry sites in Virginia. Mr. McAvoy's educational background is in materials science and engineering.
