The project area may also be considered a corridor for possible localized • movement of man and animals between the Yampa River and Colorado River drainages. The area may have been occupied or utilized by the Poleo-Indian (ca. 10,000-5000 B.C.), Western Archaic peoples (8000 B.C. -Historic Period), and the Fremont (A.D. 800-1200). Paleo-lndian Occupation 10,000 - 5,000 B.C. The earliest radiocarbon dates for occupation in the region are from the Paleo- Indian tradition. This period (often divided into the Llano, Folsom, and Plano Complexes) is characterized by the hunting of now-extinct megafauna by small nomadic groups and the use of bifacially flaked, fluted, or unfluted lanceolate points. These people occupied campsites, kill sites, and other special activity sites for short durations. Vegetal resources comprised a relatively minor part of their diet. The Llano, a late Pleistocene development on the grasslands of the Great Plains and parts of the Southwest, is the earliest of the three Paleo-Indian traditions. It is associated with mammoth hunting in the western United States and with the use of the Clovis projectile point, a finely flaked, fluted, lanceolate paint with slight tangs and regular transverse flaking. This Big Game tradition has been documented from Middle and South America to the Arctic. Regionally, in eastern New Mexico, the Clovis Blackwater Draw No. I Site yielded a mean radiocarbon date of 9220 B.C. (Willey 1966:40). The Dent Site in eastern Colorado produced a date of ca. 9200 B.C. and Clovis points in association with mammoth bones (ibid.). The Union Pacific Mammoth Kill Site in southern Wyoming is also dated about this same time (9330+ 350 B.C.) and clearly places the mammoth to the west of the Continental Divide, but no Clovis points were found in direct association (Irwin, et al., 1962:837). Haynes (1965) reports that mammoth remains and a fluted Clovis point, although not in direct association, have been found in a loess layer, Unit D, not far from the Hell Gap Site in Wyoming. The Folsom Complex apparently emerged at the decline of the mammoth and The rise of the bison on the Great Plains. P.adiocarbon dates from two Folsom sites indicate a temporal span for this tradition of about 2,000 years (co. 9000-7000 B.C.). The Lindenmeir Site of northwestern Colorado is probably the best representative of this tradition; it produced a radiocarbon date of ca. 8800 B. C. (Willey 1966:43). The • Lubbock Site in Texas produced samples dating between 7800-7300 B.C. (ibid.). The 2.8-3
