Twyfelfontein petroglyphs

The last stop on our trip was to see rock art at Twyfelfontein (Afrikaans for doubtful spring), which is suppoused to be one of the most extensive sites in Southern Africa. There were pictures of all kinds of animals, and some kinds of maps of springs. There were even some pictures of seals and penguins, supposedly from when the people living here went to the coast to find salt. The art has been dated at more or less 5000 years. I was very impressed.
