Detailed geologic map compilation using Google Earth base images has resulted in new geologic maps for four study areas exposing Plio-Pleistocene strata around Lake Turkana. These map areas (Ileret, Koobi Fora, Lomekwi and the Omo Valley) contain the discovery sites for some of the most important hominin fossils and stone tools found in the basin, and have been studied for over 50 years. In addition to a variety of geologic mapping efforts, these studies have resulted in documenting many radiometrically dated volcanic ash layers as well as paleomagnetic studies. Taken together these efforts provide strong age control for these lake margin strata. The combination of age control and detailed geologic mapping allows the presentation of map patterns cast in time rather than in geologic formations. These new maps may form a resource for targeted paleontological and archeological research.
