Haasgat is a fossiliferous South African paleocave located in the Cradle of Humankind UNESCO World Heritage Area, approx. 20 kilometres (12 mi) northeast of the hominin-bearing sites of Sterkfontein and Swartkrans and approx. 60 kilometres (37 mi) north-northwest of the City of Johannesburg. It is located on private land and is not accessible by the public.
The cave system formed on the western slope of a narrow, north-south valley excised by a southeastern tributary of the Witwatersrandspruit River. As is the case with many of the dolomitic paleocaves in the region, the system was extensively mined for lime during the early 20th century. Although this mining obliterated the original cave entrance and parts of the system, the miners largely followed the original contours of the system. As a result, Haasgat is somewhat unusual in maintaining both the original roof and parietal contours, as well as remnant fossiliferous bands of calcified sediments throughout the ~100m long tunnel that comprises the modern cave.[1][2][3]
