Major James Stevenson-Hamilton discovered the first Rock Paintings in the Park in 1911. However, the turbulent beginning of the park did not allow much time for further examination of such sites. It is only in recent years that a concerted effort has been made to document the work.
Most of the rock art sites in Kruger are located in rock shelters in the southwest of the park. There are thousands of their painting sites in southern Africa. San rock art is deeply spiritual, reflecting upon the rituals and spirit-world experiences of San ritual specialists: the !gi:xa (or shamans).
In keeping with this, the rock art of Kruger is dominated by images of those animals that the San knew to have the most spiritual power: eland, kudu, giraffe, elephant and rhino. There are some unique features about the Kruger rock art sites - relatively few human figures are depicted and those that are show strange otherworldly features, such as long streamer-like tails (the so-called vapour trail figures).
The Rock Art Research Institute believed that the Kruger paintings may be comparatively old (many centuries if not millennia) as they are on harder rock than the sandstones of other parts of South Africa. Kruger rock art, therefore, has none of the scenes of domestic animals or colonial imagery that are found in other areas, where the rock art is more recent.
Materials used include ochre, blood and ash, and paints made from naturally occurring dyes were mixed with blood, fat or egg whites. The paint was applied using fingers, feathers or simple brushes of animal hair. The rock art sites can be accessed only by taking part in the Bushman Walking Trails.
