a later group of cattle pastoralists. The main feature of this site is a series of thirteen sandy bowl-shaped depressions and mounds. These depressions, called Sirikwa Holes, were deliberately constructed as pens for securing cattle, and the low mounds that are adjacent to these hollows were created from heaping dung and refuse outside the pen.[16] The remains of cattle, goats, and sheep have been found at Site II, many of which show cut-marks and signs of human use. John Sutton's excavations in 1985 found the mandible of an equine species, possibly a donkey.[17]
