Kolo, just south of Tarangire, is where you'll find some of the most accessible Kondoa rock paintings. From the last stage of the Stone Age, these illustrations on cave walls depict hunting scenes using stylized human and animal figures. These fragile documents of an era long past were studied by Mary Leakey, who wrote a book about them called Africa's Vanishing Art. At a nearby site, Leakey discovered "pencils" in which ocher and other pigments had been ground
and mixed with grease. Later excavations revealed that some were 29,000 years old.
