Kanger Ghati National Park Madarkonta and Kodri Bahar. These are Kotamsar cave, Kailash Cave, Dandak Cave, Devgiri Cave. Many other caves were also discovered in the national park. These caves have very fine structures of dripstones i.e. stalactites and stalagmites. Chemically these formations are recrystallized calcium carbonate. These structures have taken million of years to form. Kotamsar and Kailash caves are opened for tourists and other caves are closed for tourists. Only those caves which have openings have been discovered in the National park. There are many caves which have no opening and they are yet to be discovered. As approaches to most of
Blombos Cave terrain abruptly drops down towards shoreline that lies some 34,5 meters below the cave entrance. The talus, which primarily consists of Middle Stone Age deposit, rock fall and unconsolidated sediments, is stabilised by an area of large, exposed blocks (14m²). At some stage - and in between the prehistoric occupation of the cave site - these blocks have fallen down from the rock face above, effectively preventing site erosion and allowing sediments to stabilize and accumulate in front of the cave's drip line. Calcium carbonate (CaCO3) rich ground water seeps in from the cave roof and percolates through the interior
