是一块巨大的崩积岩块，岩块棱角分明，垂直节理面清晰可见，是由于岩层中节理裂隙发育，在重力等外动力作用下发生崩塌而形成。重力崩塌是张家界地貌形成的外动力作用之一。 It is a big rock with clear edges, corners and vertical joint faces. It was formed by collapse of the stratum containing developed joint fissures under the effect of exogenic forces including gravity. Gravitational collapse is one of the exogenous forces forming Zhangjiajie landform.
