Engare Sero site (Tanzania)
Some 5,000 to 19,000 years ago, a group of people slogged their way across muddy terrain along the southern shore of Lake Natron in northern Tanzania. These footprints are located at a site called Engare Sero, near a volcanic mountain known as Ol Doinyo Lengai (”mountain of god,” in the local Maasai language). This site in northern Tanzania which contains 400 footprints and cover an area the size of a tennis court, is the largest assemblage of ancient human footprints in Africa.
