This cave doesn't get too much mention even though its only a couple of hundred meters from sterkfontein caves.
It's important because many fossil discoveries have been made here.
Broom was a regular digger and the cave has turned out to be particularly rich in hominin remains. it also has some very early uses of fire by human ancestry at 1.5 million years ago.
From the fossils discovered here it has been demonstrated that many of them were the victims of big cat depredation in the form of leopards and this saber tooth variety Megantereon

Homo habilis, amoungst the earliest of tool makers is present with the Oldowan technology.
Homo ergaster, the African equivalent of homo erectus is found here too and many of the tools from the surrounding areas are associated with this species. These are inherited and refined from the Oldowan tech. It's from Ergaster that we start to get beautiful handaxes in abundance.
The surrounding areas are littered with millions if not billions of them. I have examined tonnes of both the Oldowan and Acheulean material from these areas, having grown up there.
