Tank Rock Introduction
Tank Rock is a rock formation by the coral reef coast that resembles a tank, covered in green algae. There are large holes that penetrate through the rock, and lucky visitors may see local cattle and sheep wandering in and out, creating a breathtaking view. The geology of Lanyu primarily consists of andesitic lava and basaltic agglomerates containing hornblende, along with Pleistocene red clay layers, uplifted coral reefs, and Holocene alluvial, colluvial layers, and coastal fringe reefs. Over time, through natural processes of erosion and weathering, these have shaped Lanyu's most interesting rock landscapes. In addition to Tank Rock, other famous rock formations in Lanyu include Red Head Rock, Crocodile Rock, Twin Lions Rock, Dragon Head Rock, Old Man Rock, Elephant Trunk Rock, Mother Hen Rock, Five Holes Cave, Jade Girl Rock, Steel Helmet Rock, Warship Rock, and Steamed Bun Rock.
