Satellite photograph of the north end of Lake Turkana (Rudolf) showing the Omo River winding southwards to reach the lake by way of a birds-foot delta. Lake Turkana occupies the lowest part of a Rift Valley trough (graben). To the east of it a shelf-like area of pale-colored terrain can be seen. This is the area in which sedimentary deposits from the time range 4.5 to 1 million years are eroding so as to reveal their contained fossils and artifacts

A block diagram of the Koobi Fora (East Rudolf) area. This shows in greater detail the physiography of the area that is yielding fossil evidence of early man. Plio-pleistocene sediments are exposed over a large part of a shelf-like strip of terrain between the lake and the rim of Tertiary volcanics. The area is approximately 50 miles from north to south and 15 to 20 miles from east to west. The director of the National Museum of Kenya, Richard Lea

An air-view of the modern shoreline of Lake Turkana and the delta of the Il Eriet River. Many aspects of the situation are the same as when the fossil bearing sediments were deposited; a sandy bottomed watercourse winds its way through a silt covered floodplain to build out sand and silt banks at the river mouth. Fossils occur in situations representing all these environments of the river, but in Pliocene to early Pleistocene times, the rivers appea

The modern lakeshore floodplains of Lake Rudolf support a distinctive community of animals that are dependent on the lake for water and some grazing. There is one such species- the topee (Damaliscus lunatus).

The success of the Koobi Fora expeditions in discovering a wide range of important new fossils is largely due to the existence of a highly trained and very skilled team of fossil hunters. Their activities are coordinated by Richard Leakey and they are lead in the field by Mr. Kamoya Kimeu, who has been professionally engaged in this pursuit for more than 15 years. Here the fossil hunting team is seen in the field.

Site HAS (Fx Jj3)- volcanic ash (tuff) has filled in delta distributary channels which can be traced winding amongst floodplain deposits which were laid down just inland of the former lakeshore. Eroding out of the uppermost deposits of the channel are the bones of a single hippopotamus carcass. The volcanic ash is the KBS tuff.

Site KBS (Kay Behrensmeyer Site): (Fx Jj1)- View of the site from the adjacent gully. The beds in the foreground are deposits laid down in lagoons and swamps at the lake margin. The pale outcrop above is the KBS tuff which here fills an ancient distributary channel system that was established over the swamps as the lake retreated.
