是由并排耸立的六座高数百米的平顶石柱组成的砂岩峰林，构景岩层为泥盆系云台观组石英砂岩，由于流水沿垂直节理裂隙侵蚀及重力崩塌作用而形成，平顶是古夷平面的有力证据。

It consists of 6 flat-topped sandstone columns in a line, each one of which is hundreds of meters tall. The forming layers come from the Devonian Yuntaiguan Formation quartz sandstone. It is a result of water cutting along vertical joints and the sandstone falling down along the certain directions. Flat-topping is strong evidence indicating the ancient planation surface.
