Depression Rock Shelter site is located on the northwest side of the Female Hill. The site gets its name from the depressions that have been ground into the shelter walls. Accompanying these marks are red paintings of what appear to be cattle, as well as geometrics. The rock shelter site, dated from charcoal samples, had its earliest occupation at least 30,000 years ago. Excavations dug up LSA stone tools and Iron Age artifacts. Pottery found in the deepest layers was dated to the first century[clarification needed, and is affiliated with the oldest stone artifacts found in this area. Mongongo nut shells were also uncovered in the various deposits, including the deepest layers, which makes them the oldest mongongo nuts ever found in an archaeological context.
