In 1968 Richard Leakey established the Koobi Fora Base Camp on a large sandspit projecting into the lake near the ridge, which he called the Koobi Fora Spit. A survey and numerous excavations showed the region was a source of hominin fossils from the last 4.2 million years. Far exceeding the number of humanoid fossils are the non-humanoid fossils, which give us a look at the fauna and flora as far back as the Miocene.
