Abstract

In this paper, we describe grayish white and other chert tools from Lost Dune, a briefly occupied Late Prehistoric bison butchering camp in southeastern Oregon, and five potential sources of the cherts, using visual properties and ultraviolet fluorescence. Visual band ultraviolet fluorescence spectra of seven regional cherts support fluorescence results. Further, we characterized the five sources and 37 chert artifacts by instrumental neutron activation analysis. Of 121 tools, we have identified 67 as opalite from the Tosawihi quarry complex 300 km southeast of Lost Dune in northern Nevada, 10 as silicified mudstone from the Owyhee Breaks 110 km to the east in extreme eastern Oregon, and 26 as the local Harney Lake chert, 10 to 15 km west of the site.
