The site at Drimolen is on a grassy hillside, with limstone pits surrounded by low scrubby trees and olives. The pits are actually former caves, with collapsed roofs. Several million years ago, these caves had small vertical openings perfect for shelter our hominid relatives. Inside these caves, many died and eventually turned to fossils over the years. The Drimolen site has many layers, some of which are visible in this photo. The central pillar-like stone is a type of plug made of debris that fell into the cave from the original opening. If you look closely, you can see the white stones are all tipped in the same direction, showing how they slid into the debris pile over the centuries before hardening into the rocky plug that we see today.
