Locating archaeological sites that predate the arrival of modern sea level has been difficult along the Oregon coast. This is in part believed to be the result of geologic processes that have influenced the preservation, distribution, and visibility of sites within the Oregon coastal landscape. Because of these changes, researchers...
Coastal stream basins are of great importance to efforts aimed at refining our understanding of the earliest populations that inhabited the ancient Oregon coast. However, geomorphic responses to post-glacial sea level rise in these settings has produced depositional environments that destroy or deeply bury late Pleistocene and early Holocene-age archaeological...
The Younger Dryas climatic event is a global phenomenon associated with a 1,000 year return to glacial conditions during the late Pleistocene period between 12,800 and 11,500 cal BP. Because of its significant effects on paleoenvironmental conditions in some parts of the world, archaeologists commonly seek to assess whether the...
This dissertation serves as a contribution to the study of the prehistory of the Central Desert region of Baja California, Mexico. Between 2007 and 2011, a trans-peninsular archaeological survey and excavation program―the Central Desert Early Prehistory Project (CDEPP)―was completed for a portion of the Baja California peninsula extending from the...
The archaeological record of the First Americans is known almost exclusively from interior sites located away from coastal margins. While archaeologists hypothesize that early peoples initially migrated into the Americas along the Pacific coast, environmental changes associated with postglacial sea level rise may have destroyed or obscured such early sites....
Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Hunter-gatherers depend on naturally occurring resources and, in order to survive, must overcome resource procurement challenges inherent in their environment. One challenge relates to the temporal and spatial availability of resources, which hunter-gatherers address, in part, through the strategic use of space to position themselves for optimal access to necessary...
The incorporation of experimental archaeology into the study of lithic technologies has provided archaeologists with a framework to understand past behaviors. The analysis of stone tools has the potential to reveal morphologic characteristics unique to the manufacture, use, and maintenance of stone tools. The implementation of controlled experiments to identify...
Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...
