Early one morning, five of us climbed aboard a safari vehicle and headed into the Bushman’s Kloof wilderness of the Cederberg Mountains in South Africa’s Western Cape. This was not, however, a safari in the usual sense. We had no expectations of seeing lions, elephants, giraffes, or any of the other fabled African game animals. Instead, the guide drove us through a scrubby landscape to a gallery of ancient rock art, the legacy in rust-red of the ancient San people who once called this region home.
