为一发育在中山峰顶上的独立砂岩峰柱，是由于流水沿北东向及近东西向两组节理侵蚀、崩塌而形成。峰柱两侧陡峭，顶部较平坦，峰顶海拔1130m，呈不规则状，远观石柱直冲云霄，故称一步登天，站在峰顶可观杨家界全景。 It is an isolated sandstone column on the top of Middle Mountain that is 1130 m tall. The column has two steep lateral walls and a flat top. The column appears to extend into the sky, so it is called “Reaching the sky in a single bound”. Standing on the top of the Mountain, one can get the full view of Yangjiajie. It is a result of the water cutting along northeast and east joints and the sandstone falling down along the certain directions.
