An excavation in April 1988, led by Peter J. Mehringer of Washington State University, with a team of leading local and national authorities in Paleo-Indian Archaeology and members of the Confederated Tribes of the Colville Reservation, discovered 22 more stone and bone tools, but removed only five for laboratory study. Richey, who in November 1988 bought out his partners and became sole owner of the Clovis site, replaced the Mehringer team with New York archaeologist R. Michael Gramly, who then led another dig in October 1990. This excavation became controversial, with members of the Confederated Tribes of the Colville Reservation protesting the state government’s granting of an archaeological permit for Gramly, whose statements and writings questioned a link between Clovis Paleo-Indians and modern Indians. Gramly had also argued against new laws that, in his view, tied the hands of U.S. archaeologists in favor of protecting Indian cultural heritage. In addition, the Tribes objected to the excavation of the site for personal profit.
