Double Lion Rock Introduction
Lanyu was formed by volcanic eruptions from the sea floor, characterized primarily by andesitic lava and basaltic agglomerates. Over the years, sea erosion and weathering have left behind hard, weather-resistant rock formations that create various interesting geological landscapes. Scattered along the coast are numerous uniquely shaped rock formations, named by Han Chinese according to their shapes, such as Shuangshi Rock, Junjian Rock, Gangkuan Rock, Xiangbi Rock, Longtou Rock, Laoren Rock, Mantou Rock, Hongtou Rock, Elian Rock, Tank Rock, Yunu Rock, and Muji Rock. Each one is remarkably lifelike and vivid. The marvelous nature has sculpted the island's hard rocks as if they were made of clay, turning Lanyu into an outdoor exhibition of large stone sculptures.
