history? yes, the edge of the river is a lot of history.

in this lake there is cave depth of approximately 200 km. and above there is also a cave, inside there is kitchen equipment that has become a stone. (di dalam danau ini ada goa kedalaman kurang lebih 200 km. dan di atas juga ada goa, di dalamnya ada peralatan dapur yang sudah menjadi batu.)
