Introduction to Pagoda Reef: Pagoda Reef is named after its shape like a pagoda. It is shaped by stratigraphic fractures and formed by sea erosion over the years. It is located at the northern end of Limoba Island in Changdao County. It is 21 meters high and about 5 meters in diameter. It has a majestic shape. The pagoda reef is made of quartzite and shale alternately laminated. The stone patterns are clear and the layers are distinct. The horizontal lines from top to bottom divide the tower into dozens of layers. The vertical rock lines of cracks divide each layer. They are all divided into several sections, as if the tower is not a strict whole, but a loose building made of stones of different sizes and shapes. About 3 meters above the high tide level, the pagoda has a ring of fractures, suspending 1/3 of the entire tower in the air, making it look particularly majestic.
