Ancient rock painting is distinctive from petroglyphs. Petroglyphs are carved into the rock surface. Rock painting is far less permanent and quite rare compared to the number of preserved petroglyphs. The conditions that will preserve the very fragile painted images over hundreds and sometimes thousands of years are usually confined to caves or protected rock overhangs. You can see the moisture seeping into this overhang as is evident from the ferns and moss growing in the cracks. The paintings are faint but evident from the reddish colored substance used as paint.
