此处象形石为凝灰质砾岩，节理裂隙发育，在风化剥蚀、流水侵蚀等外力作用下，沿着两组主要节理裂隙面球状风化，岩石突出的棱角逐渐缩减，边缘光滑，形似一只俏皮的石龟。 The grotesquely-shaped rock here is tuffaceous conglomerate, and joints and fissures are developed. Under the action of exogenic forces such as weathering erosion and water erosion, the two main groups of joints and fissures are weathered spherically. The protruding edges and corners of the rock are gradually weathered with smooth edges, looking like a nifty rock turtle.
