TITLE: Results of recent archaeological investigations at the Kelly Forks work center, north fork of the Clearwater river, North Central Idaho

ABSTRACT: University of Idaho archaeologists conducted field schools in summer 2010 and 2011 at the Kelly Forks Work Center, a multi-component prehistoric site located at the confluence of Kelly Creek and the North Fork Clearwater River on the Clearwater National Forest. A suite of 10 radiocarbon dates, with calibrated ages beginning over 11,000 years ago, has documented evidence of recurring occupations from the early Windust phase (ca. 11-8000 years ago) into the historic period. Concentrations of flaked lithic tools, cobble tools, and debitage indicate diverse onsite activities including tool manufacture and modification, fishing, hunting, and processing game animals. Protein residue analysis has identified bison, rabbit, human, and beaver/porcupine antisera. X-ray fluorescence analysis indicates that obsidian and vitrophyre were obtained from multiple sources in south Idaho, western Montana, and central Oregon. These and other ongoing investigations indicate that the Kelly Forks Work Center site represents the most significant early prehistoric occupation on the upper North Fork.
