Between the Ngorongoro Conservation Area and the Serengeti National Park there is an outstanding natural beauty, highly recommended: the so-called Olduvai Gorge, a ravine about 100 m deep and 48 km long.
Since 1930s, Louis Leakey and his wife Mary, both Kenyan anthropologists of English origin, have discovered in Olduvai’s layers hominin remains from different prehistoric periods, included those of the Australopithecus Boisei, estimated at 1.75 million years old and who exclusively inhabited this area.
The so-called beds, namely layers, brought many bones to light giving researchers the opportunity to make considerable progress in studying the evolution of the human species.
On the ledge close to the gorge, a Masaai guide explains the history of this compelling site and next to it you can visit the small newly renovated museum where the most significant remains are collected and explained.
In 1972 Mary Leakey found hominin footprints about forty kilometres far from Olduvai, in Laetoli. They were left by two adults and a child and was dated at 3.5 million years old. It is possible to see their cast in the museum, but unfortunately the site cannot be visited.
