During the GPS Division's recent student field trip to South Africa a stop was made at the pinnacle, a quartzite column at the Great Escarpment to the west of Kruger National Park. The Great Escarpment features nearly 500 meters (1600') of elevation change over just a few kilometers. The base of the escarpment is often enshrouded in misty clouds, giving the impression that one is standing at the edge of the world.
