Crocodile Rock Introduction
Crocodile Rock is formed from volcanic debris, shaped by the erosion of coral reefs and crustal movements, resulting in rock fractures that resemble the rough skin of a crocodile. The rock protrudes from the coastline, opening its mouth to the sky and revealing two rows of sharp teeth, thus earning its name. The geological layers of Orchid Island consist mainly of andesite lava containing hornblende and basaltic agglomerates, as well as Pleistocene red clay, raised coral reefs, and Holocene alluvial, colluvial, and coastal fringe rock layers. Through the natural processes of marine erosion and weathering, these elements have shaped the most fascinating rock landscapes of Orchid Island. The Tao people (Yami people) refer to Crocodile Rock as ji-macingeR, describing its elongated rock formation that looks as if it has been tightly cinched in the waist, forming a slender shape. Often, flocks of sheep can be seen climbing the rock, creating an interesting scene as if they are being swallowed by the open mouth of the crocodile. Besides Crocodile Rock, other famous rock formations on Orchid Island include Red-headed Rock, Battleship Fish Rock, Twin Lions Rock, Dragon Head Rock, Old Man Rock, Hen Rock, Jade Girl Rock, Five Hole Cave, Tank Rock, Steel Helmet Rock, and Bun Rock.
