Dissertation/Thesis Abstract

A Spatial Approach to Predicting Prehistoric Tongva (Gabrielino) Archaeological Deposits in the Los Alamitos Bay Area of Southern California
by Brennan, Candice Marie, M.A., California State University, Long Beach, 2020, 90; 27736209
Abstract (Summary)

The regional prehistory of Long Beach in Southern California is partially understood compared to further regions of North America. The detail of prehistoric settlement around Los Alamitos Bay were not well documented due to rapid urban development throughout the twentieth century. In the archaeological record documented settlement research was comprised of limited investigation and survey work in the area. It was documented that prehistoric populations used available natural resources and practiced a generalized subsistence. Over the course of the Holocene, communities responded to changing conditions which caused mobile populations to adapt to sedentism.

This thesis addresses the nature of coastal settlement through the investigation of settlement data for the Los Alamitos Bay area. Using a review of archaeological information over the last sixty years, a spatial analyst model of settlement was generated that summarized the current understanding of how prehistoric communities were spatially distributed across the environment of Los Alamitos Bay. The archaeological data were derived through a records search of seventy-six documented cultural deposits. The records included survey and excavation work of documented cultural deposits. Published documentation detailed how prehistoric populations were distributed across the landscape and availability resources.

A systematic review of cultural deposit information was investigated and characterized in order to develop a spatial analyst model to provide information on past human behavior around Los Alamitos Bay. The study area was selected because it provided data required to associate archaeological theories to GIS grounded research methods. The results reveal that cultural deposits were located near water resources. The generated GIS spatial analyst model detailed areas where there are potentially low, medium and high probabilities of finding areas of cultural deposits around Los Alamitos Bay. Of the total 47,432,892 (100%) square meters of the study area, the potential for cultural deposit areas fall within 3,774,079 (8%) of the study area. Of the total 37,285,788 square meters of the modern land use area, the potential for cultural deposit areas fall within 3,774,079 (10%) square meters. Residential, Commercial and Recreation are the top three modern land use areas that have potential for cultural deposits. The spatial analysis assisted in the interpretation of the local prehistory and provided insight on locations of potential deposits that can be applied to future research questions or CRM planning.
