The Olduvai Gorge is a steep-sided ravine in the Great Rift Valley that stretches through eastern Africa. It is about 48km long.

Where is it located?

 
It is located in the eastern Serengeti Plains in northern Tanzania and located 45 km from the Laetoli archaeological site. 

Why is it important?

 
The area of Olduvai Gorge is one of the most important prehistoric sites in the world for research and understanding of the early human evolution.

Hominid fossils(preserved bones) and stone tools found in the Olduvai Gorge. They have been found to cover an astonishing time span of as early as 2 million years ago up to the relatively recent 15,000 years ago. This is the longest lineage of human evolution found anywhere on earth. Due to this reason sometimes this important prehistorical site is called "The Cradle of Mankind".
