“…Following arguments that have developed over much of the twentieth century in reference to fluted point occupations in eastern North America (Goodyear, 1989;MacDonald, 1968;Meltzer, 1984Meltzer, , 1988Meltzer, , 1989Witthoft, 1952), Paleoindian archaeologists on the Plains generally infer that such material was obtained during visits by entire residence groups to the geologic source(s) of these materials, and thus that the locations of these sources relative to the location where the artifacts being studied were recovered offer a measure of the size of the areas within which these groups moved (i.e., Amick, 1996;Bement, 1999;Hofman, 1991Hofman, , 1992Hofman, , 2002Hofman, , 2003Meltzer, 2006). In the east, where this argument first developed, it is now clear that the proportion of non-local material in Paleoindian assemblages varies enormously from site to site and region to region (Lothrop, 1989;Meltzer, 1984Meltzer, , 1988Tankersley, 1998), if raw material use monitors range sizes, eastern Paleoindian ranges were not uniformly, or even predominantly, unusually large.…”
