Most of the studies in the Bir Kiseiba region relate to the beginning of the Holocene when there was a wet period from about 11-10,000 BP until 5000 BP. There were two digging seasons at Bir Kiseiba, one in 1979 and the second in 1980. A total of 13 localities were excavated, scattered among four playas in the Bir Kiseiba region.
