The East Wenatchee Clovis Site (also called the Richey-Roberts Clovis Site or the Richey Clovis Cache) is a deposit of prehistoric Clovis points and other implements, dating to roughly 11,000 radiocarbon years before present or about 13,000 calendar years before present, found near the city of East Wenatchee, Washington in 1987. Accidentally discovered in an apple orchard, by Mark Mickels (National Geographic, 1988) it yielded some of the largest stone Clovis points known to science. After controversy over its excavation, the site was sealed off from further digging from 1992 until 2007. == History == The site was accidentally uncovered by Mark Mickels, and also by farmworker Moises Aguirre Calzada on May 27, 1987, while installing an irrigation line. His digging unearthed about two dozen stone bifaces, which were at first mistaken for tools left by contemporary Indian tribes. Orchard co-owner Rich Roberts and his wife Joanne later showed the items to local amateur archaeologist Russell S. Congdon, who identified them as Clovis tools and subsequently contacted archaeologist Robert Mierendorf. The tool kit manufactured by the Clovis culture is one of the earliest known in the Americas, persisting from about 11,050 to 10,800 radiocarbon years BP. The site was named by National Park Service archaeologist Robert Mierendorf, the first professional scientist to examine the cache. After the Robertses and their orcharding partner Dr. Mack Richey opened the site to further study, beginning in 1988, it was referred to as the Richey-Roberts Clovis Site and, later, the Richey Clovis Cache. 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 (see below). In light of the dispute, Gramly’s dig proceeded on a shortened time frame, and ultimately removed approximatively 69 artifacts including tools, debitage, and bone fragments before closing the site. An uncertain number of items, including two more bone artifacts, were left in place. In 1992 Richey donated all the recovered Clovis artifacts and sold the archaeological rights to the 35-square-meter site for $250,000 to the Washington State Historical Society, which owns them in perpetuity. The sale contract stipulated that no archaeological work could take place for 15 years after the purchase; that moratorium expired June 1, 2007, although no new scientific digging has since taken place. Richey sold the entire orchard to a new owner in 2004. At this time the what was once an archaeological site is re-filled with dirt, covered with a cement slab, and restored to be part of the orchard. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「East Wenatchee Clovis Site」の詳細全文を読む スポンサード リンク
