Tanzania is well-known for its archaeological sites, some of these sites yielded very important fossils that enlighten us about the origin of mankind. The majority of important sites are located in the north of the country but in the south, some 20km from Iringa (40minutes) is the important Isimila stone age site.
In the late 1950’s archaeologists unearthed some of the most significant stone age finds ever identified. Most of these finds were tools, estimated to be between 60 000 and 100 000 years old. They also found fossilized bones of mammals; an extinct hippopotamus and something similar to the modern day giraffe but with a shorter neck.
There is evidence which shows that the area around the Isimila site was a small lake. This would have been a perfect hunting ground for hominids who lived there between 300 000 to 600 000 years ago. The tools found there confirm this theory. Looking at the site today you might be able to imagine how the land was eroded from a lake to a large canyon. Harder rock types more resistant to erosion has remained, leaving thin rock towers as high as 30m.
The site is easily accessible from Iringa and the guides are located at the museum itself. It makes a good half day trip, but try to get there in the early morning – when the sun comes out the canyon it can get unbearably hot. The tour should take about three hours. There is a little picnic area and toilets are found at the museum.
