Dragon Head Rock Introduction
The geological layers of Lanyu are mainly composed of andesitic lava containing hornblende and basaltic breccia, along with Pleistocene red soil layers, uplifted coral reefs, and Holocene alluvial layers, debris flow layers, and coastal fringing reefs. Through natural processes of coastal erosion and weathering, Lanyu has been shaped into a landscape filled with fascinating rock formations. The formation of Longtou Rock is a large uplifted coral reef rock that has gradually taken on its current appearance due to natural coastal erosion and weathering. The Tao people (Yami people) refer to Longtou Rock as ji-mazicing, meaning the rock is sharp and irregular, forming pitted walls. The waters near Longtou Rock are an important and rich fishing ground for the people of Lanyu, and local residents can often be seen fishing there. More travel precautions for Lanyu.
