Environment and Activity Patterning at Isimila Korongo, Iringa3

Two differing fluvial environments from Sands 3, Isimila, yielded distinct lithic assemblages. One occurrence, on the sands of an occasionally active channel flat, indicates occupation of the anastomose channel with associated shrubby vegetation by a group whose lithic artifact inventory is dominated by large cutting edge tools. The other, on a low interfluve flanking a channel, with abundant herbaceous vegetation, yielded numerous scrapers and relatively few heavy duty tools. It is suspected that the variations in microenvironment are related to the composition of the lithic artifact inventory.
