Crocodile Rock Introduction
Crocodile Rock is formed from volcanic ejecta, and due to the erosion of coral reef seawater along with tectonic changes, the rock's joints have fractured, resembling the rough skin of a crocodile. The rock protrudes from the coastline, opening its mouth skyward and revealing two rows of sharp teeth, similar to a crocodile, hence its name. The geological formations of Orchid Island mainly consist of andesitic lava containing amphibole and basaltic conglomerates, along with Pleistocene red soil layers, uplifted coral reefs, and Holocene alluvial and colluvial deposits, shaped by the natural processes of marine erosion and weathering, creating the most intriguing rock formations on Orchid Island. The Tao people (Yami) refer to Crocodile Rock as ji-macingeR, describing its elongated shape, resembling a narrow section that has been tightened. Often, flocks of sheep can be seen climbing the rock, appearing as if they are being swallowed by the open mouth of a crocodile, creating a quite interesting scene. In addition to Crocodile Rock, Orchid Island is also famous for other unusual rock formations, including Red Head Rock, Battleship Fish Rock, Twin Lions Rock, Dragon Head Rock, Old Man Rock, Hen Rock, Jade Girl Rock, Five Holes Cave, Tank Rock, Helmet Rock, and Bun Rock.
