Tank Rock Introduction
Tank Rock is a geological wonder located by the coral reef coast, resembling a tank covered with green seaweed. The rock has large holes that penetrate through it, and lucky visitors may spot local cows and sheep moving around, creating a breathtaking scenery. The geological layers of Lanyu are primarily composed of andesite lava and basaltic conglomerate containing hornblende, as well as Pleistocene red soil layers, uplifted coral reefs, and Holocene alluvial, colluvial, and coastal fringe deposits. The processes of marine erosion and weathering have shaped Lanyu's most intriguing rock formations. Besides Tank Rock, other famous rock formations in Lanyu include Red Head Rock, Crocodile Rock, Twin Lion Rock, Dragon Head Rock, Old Man Rock, Elephant Trunk Rock, Hen Rock, Five Holes Cave, Jade Girl Rock, Helmet Rock, Battleship Rock, and Bun Rock.
