Site HAS- plans and sections of the findings. Left: a plot of the location of bone specimens including the hippo bones on the surface. Right: a plot of the location of stone artifacts. Center: two slices through the site showing how the material forms a horizon representing an old ground surface.
Site KBS (Kay Behrensmeyer Site): (Fx Jj1)- View of the site from the adjacent gully. The beds in the foreground are deposits laid down in lagoons and swamps at the lake margin. The pale outcrop above is the KBS tuff which here fills an ancient distributary channel system that was established over the swamps as the lake retreated. The early prehistoric occupants of the site camped on the sandy substratum provided by the tuff filled channel.
Site KBS (Kay Behrensmeyer Site): Excavation in progress. The consolidated fine, grey tuff dust that fills the swale left by the abandoned channel is being gently chipped away to uncover the top of the sandy streambed.
Site KBS (Kay Behrensmeyer Site): The consolidated deposits are dug in 5 cm increments by tapping a small chisel. The lumps and crumbs of tuff are broken on a board with a rubber mallet and then sent for screening. Almost all material is found while still in place as excavation proceeds. Excavator, Mr. J. Kimengech of the Kenya National Museum.
Site KBS (Kay Behrensmeyer Site): Shows the base of the pale grey tuff dust layer being "peeled" off the tuff sand layer to expose the archaeological horizon at the interface. Excavators, Mr. J. Barthelme, University of California and Mr. Msau of the National Museum.
