At 3.9 meters, a gravel lens seals the site, with all deeper material being pre-Clovis in age (Lopinot et al. 1998:41). Two finds below this level have thrown the spotlight onto the Big Eddy site. One is a large tabular stone, possibly an anvilstone, broken into three pieces and the other is a large cobble (Bush 2006; Chandler 2001b; Ray et al. 2000). Both of these artifacts display evidence of possible human modification. In addition, the gravel layer contains many flakes.
