Late Prehistoric Technology, Quartzite Procurement, And Land Use In The Upper Gunnison Basin, Colorado: View From Site 5gn1.2, Jonathan Mitchell Peart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis presents the results from archaeological test excavations at site 5GN1.2. The focus of this research is to evaluate Stiger’s Late Prehistoric settlement-subsistence hypothesis. According to Stiger, post-3000 B.P. occupations of the Upper Gunnison Basin were limited to big-game hunting forays originating from base camps located outside of the basin. Test excavations at 5GN1.2 documented archaeological deposits reflecting aboriginal occupation during the Late Prehistoric between about 3000 and 1300 years ago. Archaeological features include four hearths associated with abundant small-mammal remains, burnt plant seeds, stone tools and stone tool manufacturing debris.

Archaeological evidence rules out site 5GN1.2 as a …

La-Icp-Ms Analysis Of Quartzite From The Upper Gunnison Basin, Colorado, Bonnie L. Pitblado, Molly Boeka Cannon, Hector Neff, Carol M. Dehler, Stephen T. Nelson

Sociology, Social Work and Anthropology Faculty Publications

We report the results of LA-ICP-MS analysis of 402 quartzite samples representing 48 collection loci in the Upper Gunnison Basin (UGB), Colorado and determine the extent to which the sources can be geochemically discriminated from one another using this non-destructive technique. The ability to differentiate among the sources would open the door to provenance studies of the quartzite chipped-stone tools and debitage that constitute 95% or more of most of the 3000-plus prehistoric site assemblages documented in the UGB. Our samples represent prehistorically quarried and non-quarried quartzite sources, including outcrop (primary) and gravel (secondary) deposits. The results reveal spatial and …
