Across The Snake River Plain: Terminal Pleistocene, Early Holocene, And Early Middle Holocene Land-Use In Southeast Idaho, Jennifer Finn

All Graduate Theses and Dissertations, Fall 2023 to Present

The range of mobility demonstrated to overcome challenges with resource distribution is a hallmark of hunter-gatherer societies. Previous studies in southeast Idaho have investigated the possibility that precontact human movement was impacted by climatic differences. According to preliminary studies on regional obsidian toolstone conveyance, land use patterns were already changing throughout the early Holocene due to increased aridity. However, the geographical distribution of Northern Side-notched projectile points suggests a significant expansion in mobility at the early Holocene/middle Holocene transition. This thesis tests the hypothesis that precontact early middle Holocene human mobility in the study area was conditioned by environmental factors …

Debitage Attributes, Obsidian Source Analysis, And Prehistoric Mobility In Southeastern Idaho, Ben Joaquin Zumkeller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study is to complement existing knowledge on prehistoric mobility in eastern and southern Idaho. I add specific detail regarding the use of Skull Canyon and its well-known Birch Creek rockshelters during hunter-gatherers’ logistical foraging rounds.

In addition, my research is a case study in combining debitage attribute analysis and intensive toolstone sourcing to read prehistoric mobility. Prior research has looked to obsidian toolstone sourcing to understand prehistoric eastern and southern Idaho mobility. However, no prior research has involved sourcing an entire, stratified assemblage of prehistoric debitage.

I collected flake attribute data from all 2,846 pieces of …
