KRAUS Entitled Ever Upward? Intensification On The Western Divide: Lithic Assemblages In An Evolutionary Perspective be accepted in partial fulfillment of the requirements for the degree of MASTER OF ARTS Christopher T. Morgan, Ph.D., Advisor Geoffrey M. Smith, Ph.D., Committee Member Scott A. Mensing, Ph.D., Graduate School Representative David W. Zeh, Ph.D., Dean, Graduate School December, 2016 i ABSTRACT Analysis of flaked stone assemblages from four study sites on the Western Divide illustrates changing patterns of hunter-gatherer land use in the southern Sierra Nevada during the Late Holocene. At the macroregional scale this investigation points to similar behaviors in raw material use and reduction trajectory across the study sites and greater southern Owens Valley-southern Sierra Nevada region; specifically, a focus on a highly curated obsidian bifacial technology in tandem with limited use of more locally available, non-obsidian toolstones. At the local scale, results elucidate the relationship between the lithic assemblages and site use by suggesting the time depth of intensive versus non- intensive occupations. Residential sites in the foothills of the western slope of the Sierra appear to represent less labor-intensive occupations. Sites just below snowline and at higher elevations represent a more intensive pattern of seasonal occupation that appears to have relied on more labor-intensive, less efficient behaviors that became increasingly so over time. The pattern of increasingly intensive use of elevation-linked ecozones through time is a common hunter-gatherer pattern seen across the Sierra Nevada and central California, albeit at a scale that is difficult to extract from larger macroregional patterns in lithic technological organization. ii ACKNOWLEDGEMENTS This research was funded in part by the Splatt Scholarship, awarded by the Anthropology Department for the 2014-2015 academic year. Without it, my large obsidian hydration sample and numerous visits to the study area in Sequoia National Forest would not have been possible. There are number of people who have made my journey through the MA program possible. I would like to thank my many family members, friends, and coworkers who have provided support and constructive feedback throughout the creation of this document. Foremost among these people are Lynne Graziadei, Stephen Bushy, Jeanne Goetz, Jason Coats, Dave Harvey, and all my coworkers at the Sacramento District Corps of Engineers. A number of other people have made this study possible. Linn Gassaway, formerly Hume Lake and Western Divide archaeologist for the Sequoia National Forest, provided guided tours to my study sites and volunteered an immense body of information about archaeology on the Western Divide. Several seasons of Forest Service volunteers and members of the Backcountry Horsemen helped to generate the collections I used, and I would like to thank them for their efforts. Others have been extremely supportive throughout my study, whether pointing me to documents or simply listening to me prattle on about my project. They include the following: Karen Miller, Alexander “Sandy” Rogers, Nathan Stevens, SWCA’s Pasadena office, Kelly McGuire, and all those who attended the southern Sierra data-share meetings. iii At UNR, I would like to thank my committee, Dr. Christopher Morgan, Dr. Geoffrey Smith, and Dr. Scott Mensing, for their patience and guidance throughout this process. Most importantly, I would like to express my gratitude to my classmates at UNR. This journey would not have been possible without you! iv Table of Contents ABSTRACT
