 Oldupai Gorge...

Olduvai Gorge- the archaeological site also known as "The Cradle of Mankind”,  is about 50 km  long.

This Gorge is one of the most important prehistoric sites in the world and has been instrumental in furthering the understanding of early human evolution.

Shifting Sand.

 The actual height from the top of shifting Sand to the ground is seen well here. some of my colleagues walked down and destroy the shape of the sand but in few minutes was returned to the normal shape. Its a place to visit.
These sand tend to move slowly and it is hard to observe it in one day or a week but if you go there every month you will discover the changes, Average sand move 17m per year. but what you can see in few hours if you stay there and there is enough wind is all the footprint of yours or anything that went up few minutes will be erased.
