The Ngorongoro Conservation Area also protects Oldupai or Olduvai Gorges, situated in the plains area. It is considered to be the seat of humanity after the discovery of the earliest known specimens of the human genus, Homo habilis as well as early hominidae, such as Paranthropus boisei.
The Olduvai Gorge is a steep-sided ravine in the Great Rift Valley, which stretches along eastern Africa. Olduvai is in the eastern Serengeti Plains in northern Tanzania and is about 50 kilometres (31 mi) long. It lies in the rain shadow of the Ngorongoro highlands and is the driest part of the region. The gorge is named after 'Oldupaai', the Maasai word for the wild sisal plant, Sansevieria ehrenbergii.
It is one of the most important prehistoric sites in the world and research there has been instrumental in furthering understanding of early human evolution. Excavation work there was pioneered by Mary and Louis Leakey in the 1950s and is continued today by their family. Some believe that millions of years ago, the site was that of a large lake, the shores of which were covered with successive deposits of volcanic ash. Around 500,000 years ago seismic activity diverted a nearby stream which began to cut down into the sediments, revealing seven main layers in the walls of the gorge.
My most favorite member of the antelope family is the eland, which also happens to be the world’s largest antelope. Though heavy, it has the endurance to maintain a trot and can jump a 4-feet fence from a standstill. My first encounter with an eland was in October 2011 in a lodge adjoining a national park in Arusha. The lodge has a watering hole and various types of animals would go there in the afternoon to drink water especially during the drier months...
Driving in the parks is allowed between 6 am and 6 pm only.
The speed limit in the parks is 50km/h and 25km/h in the Ngorongoro Crater.
Animals always have the right of way.
Never feed animals. It will upset their diet and lead to an unnecessary dependence on people.
