After Serengeti, our exciting journey continues to the to the Oldupai gorge. You may know it as Olduvai, with a ‘v,’ but once there we are told that the correct pronunciation is Oldupai, with a ‘p.’ However it’s pronounced, it’s the site of the oldest preserved human footprints anywhere. Three humans (and countless animals) left tracks in the mud here as they escaped the fury of an erupting volcano a couple of millions of years ago. Some of the oldest bones and human made objects are also found in this area. Sort of exciting to think back about these ancestors of ours, and imagine what their lives were like.
