Sterkfontein fossil site

We had the opportunity to go down into an actual cave at the Sterkfontein fossil site.  We had to put on hard-hats, and had a long long long staircase down into the cave.  There is a small interpretive museum at the site, as this was the place that found the first full austrolopithicus skull (known as Mrs. Ples).  This is also the site most rich with austrolopithicus finds in the world.  We also got to view the working site where Mrs. Ples was found, with a series of narrow walkways 20-30 feet above the site used by scientists to manage the dig.
