The conglomerate terrace by Beinan Creek north to Liji Bridge was formed by plate press and plate rise. The eastern cliff wall of the terrace is highly permeable and was easily cut through by the river. The resulted towering peaks have earned a nickname "Little Huangshan" for its resemblance to Huangshan in China on a much smaller scale. It is also called "Taitung Chibi (Red Cliff)." Little Huangshan presents a rare geographical landscape of world-class in Taiwan.
