I was really excited when I won this one on Goodreads.

Unfortunately the author ticked me off when in the first two pages he recalls when he and a friend sheltered in a cave during a sandstorm containing some tribal paintings and brags about leaving trash and human waste for future visitors to discover. A paragraph later they are digging up the body of a Bushman and looting his meager belongings in search of diamonds. Appalling behavior, especially from a scientist.
