Prehistoric and historic subsistence-settlement patterns on the central Alaska Peninsula, Alaska

The Alaska Peninsula, Alaska, is the home of three major historic hunter-gatherer cultures --- the Alutiit, the Central Yup'ik, and the Unangan. Regional questions pertaining to the subsistence-settlement patterns of the late prehistoric and historic inhabitants of the central Alaska Peninsula have not yet been fully entertained. At the same time, the region holds excellent potential for answering important questions about subsistence strategies and places. This dissertation examines the archaeological, ethnographic, and environmental record bearing on the lifeways of the people of the central Alaska Peninsula during the past 1,000 years. The primary focus is on creating and testing predictive models of subsistence-settlement behavior of the inhabitants of the Peninsula, in order to determine which location model or models have value for predicting habitation sites on the central Alaska Peninsula. A socioeconomic approach utilizing a modified gravity model developed by Jochim (1976) is first applied to the study region. Secondly, a hybrid model that incorporates aspects of the Jochim model but also includes environmental variables is developed using logistic regression analysis and Geographic Information Systems (GIS). The independent variables distance to nearest anadromous stream, aspect, distance to the nearest caribou herd, distance to the coast, elevation, distance to the nearest freshwater stream, slope, surficial geology, and soils are found to have the best predictive value for habitation site location on the Peninsula. Both models are evaluated by application to the central Alaska Peninsula study area. The logistic regression model is found to have predictive value, while the Jochim model holds some predictive value if modified to incorporate precise species distributions in a GIS application. The Logistic Regression model correctly classifies about 80% of the habitation sites within a 20% mapped area, representing a high gain model. A GIS archaeological probability surface produced by logistic regression will provide future archaeologists a prospecting tool for the Alaska Peninsula.
