砂岩经过漫长的流水切割、差异风化、重力崩塌等外营力作用，便形成了现在所看到的峰林峡谷，峡谷中两座峰柱一前一后，底座相连，犹如一只神鸡在啄石。The sandstone went through long-term act of exogenic processes such as water cutting, differential weathering and gravitational collapse and formed the valley with peak forest. The two stone pillars, whose bases are connected, resemble a pecking rooster.
