Hunter-gatherers, mobility, and obsidian procurement: A view from the Malheur Headwaters, northeast Oregon

The purpose of this thesis is to determine if there was shift in hunter-gatherer mobility strategies in the Malheur Headwaters, Oregon during the Middle and Late Holocene. It will be proposed that changes in mobility are linked to shifts in resource productivity and the intensification of root plant resources. Hunter-gatherer movement will be measured by examining changes in source-to-site distance, source variability, and procurement range size. Principles of human behavioral ecology will be used to connect changes in hunter-gatherer mobility to the intensification of root plant resources.
