Mumba Cave, located near the highly alkaline Lake Eyasi in Karatu District, Arusha Region, Tanzania.

That being said, work of the Kohl-Larsens has been seen as very accomplished due to their attention to detail, especially when one considers that neither was versed in proper archaeological techniques at the time of excavation.

[5] The site has since been reexamined in an effort to reanalyze and complement the work that has already been done, but the ramifications of improper excavations of the past are still being felt today, specifically in the unreliable collection of C-14 data and confusing stratigraphy.

It has been noted to contains remnants of obsidian, ostrich eggshell beads, fireplace wood, pottery sherds, and arrowheads that are similar to those fashioned by the Hadza people.

[5] Bed III contains a particular rich assemblage with the presence of a kitchen midden made of several animal bones and broken pottery.

[5] M.J Melhman attributed this bed to what he called the transitional "Mumba Industry" which contains both hallmarks of the Middle and Late Stone Ages.

However, after reanalysis of Bed V, several archaeologists have suggested that the assemblages found within are better assigned exclusively to Late Stone Age technology.

Along with the nearby lake, the cave is surrounded by various types of terrain including the Serengeti Plains to the west, as well as the Mubulu and Yada Highlands to the east.

Additionally, after paying closer attention to the faunal remains, several archaeologists have been able to conclude that the Mumba's past inhabitants took advantage of the terrestrial environment as well.

Bones of several animals including baboons, rabbits, warthogs, dik-diks, lizards, and snakes have been found at the site suggesting exploitation of the nearby grassland, and terraces.

This discovery included twelve males, one female, three children, and two unknown individuals ranging from as young as two up to sixty years of age.

Characteristics of modern human behavior include an increase in cognitive ability, evidence for the use of symbolism, and the origin of language.

[9] Examples of modern human behavior at the site include the presence of red ochre, the lithic artifacts, the wall art on the caves, and the overwhelming number of ostrich eggshell beads.
