A closer view of the fault scarp plus a Pleiocene volcano, Mozonik, that projects through a flood of lavas. Behind is the active volcano Lengai which has been built up entirely since the period in which the Peninj beds were deposited.

The fault scarps cut the Lower Pleistocene Peninj Group sediments so that some outcrops are down in the Natron trough as seen here, while others over large areas of the plateau above. The Peninj australopithecine jaw was found in the eroded area seen here.

Diagrams illustrating the stratigraphy and dating of the mandible. It was stratified below one lava dated at 1.3 million years and also below another one with normal polarity. This suggests Olduvai event age 1.8 - 1.6 million years (see Isaac and Curtis, 1974).

An Olivine basalt flow in Humbu Formation tuffs. These tuffs are equivalent to the tuffs just above the mandible. The potassium-argon age of the lava thus helps to date the mandible (Isaac and Curtis, 1974).

Excavations nearby disclosed the existence of a dense patch of artifacts that had not yet been cut into by erosion. This patch has a diameter of 12 - 15 m. and contains more than a tone of stone, which was apparently imported by early man. This is the site of DE/89 horizon B. The material has been concentrated by current action in part of the seasonal streambed in which the early humans camped.
