Old Montenegro is one of the typical volcanoes in China, the highest of 14 volcanoes. The mountain is towering, at an altitude of515.9 meters, and the mountains and forests are mostly composed of black pumice. The surrounding area of old Montenegro is a lava platform with a total area of 65 square kilometers. The lava that spewed out of the white river flows southwards, forming a 10-kilometer-long "stone dragon". The scene of the stone dragon is rare in the world, looking like the rough waves of the sea from afar, and the myopia is strange, thousands of shapes, vivid and strange, such as bears, tigers, snakes, ropes, and giants. The strange lava dark channels, lava cavities, and the strange lava bell milk, such as horn cones like spines like blades or thin plates, such as the four walls of the cave, are wonderful places to view the lava morphology.
