Rammang-Rammang karst

Rammang-Rammang Geopark is an area of 45,000 hectares (45 square kilometers) in the Maros-Pangkep karst mountain range in Salenrang Village, Bontoa District, Maros Regency, South Sulawesi Province, Indonesia, or about 40 km north of Makassar City. This is the third largest karst after Tsingy in Madagascar and Shilin in China.

Rammang-Rammang Geopark National Park includes karst mountains, forests, lakes, caves, prehistoric paintings, rivers and traditional villages. The site is not too far from Sultan Hasanuddin Makassar International Airport and only a few meters from the Maros-Pangkep axis road.

Karst is formed due to the process of dissolving a carbonate rock and producing a unique surface form in exokarst and indokarst. The mountains are vast and all are enchanting where many peaks loom alone and in groups. These karsts are in the middle of a stretch of rice fields with the beautiful Pute river flow.

This area has at least 268 caves with beautiful stalagmites and stalactites. It is more special that 89 of them are prehistoric caves which have frescoes by ancient people. These paintings are made from the incision of their palms.

The longest and deepest cave in Rammang-Rammang is shaped like a well. The deepest cave is 260 meters in Leaputte Leang, while the longest is Gua Salukkan Kallang for 2,700 meters.

The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...
