Middle Paleolithic Hominin Lake Environments In Saharan North Africa, Cynthia Anne Bradbury
Middle Paleolithic Hominin Lake Environments In Saharan North Africa, Cynthia Anne Bradbury
Boise State University Theses and Dissertations
Contemporaneous with the transition to biologically modern humans was the episodic change from wetter to drier environments in the Egyptian Sahara. At Bir Tarfawi, White Lake sediments represent a wet phase occurring prior to the last interglacial in the now hyperarid Egyptian Western Desert. One hypothesis for the development of Western Desert Pleistocene lakes was that the northward migration of the Intertropical Convergence Zone (ITCZ) provided a path for summer-constrained, Atlantic-sourced precipitation resulting in local precipitation. Oxygen and carbon stable isotope analysis of climate proxies such as the gastropod, Melanoides tuberculata, indicate precipitation and groundwater sources as well as the …

Recent Archaeological Investigations At Three Island Crossing: Insights Regarding Late Archaic Diet Breadth And Mobility, Meghan Kim Eastman
Boise State University Theses and Dissertations
In 1986 and 1987, an important Late Archaic period site was excavated at Three Island Crossing (10-EL-294), near Glenns Ferry, Idaho. As ethnographic reports depict extensive reliance upon salmon for winter consumption (Steward, 1938; Murphy and Murphy, 1960) the recovery of 19,000 fish remains was significant. Analysis of this assemblage demonstrated that the minimum number of individual fish recovered was around 300. Equally important were radiocarbon analyses that identified three distinct Late Archaic occupations. Of note was the recovery of a structure and storage suggesting semi-permanent residence. A subsequent excavation was undertaken at Three Island Crossing in 2008 to determine …
