岩石遗迹：“蟒蛇出洞”

依稀0204

        在这“一线天”的嶂谷西侧，见到岩壁上有一条“白蟒”张着大口惟妙惟肖。其实它不是蟒蛇的化石，而是组成岩壁的白云岩中，由于燧石条带不规则分布，经风化后形成突出在岩壁上的一种拟态。

        On the west cliff of the narrow gorge, there is a vivid white boa-like pattern. Actually, it is not a real fossil boa, but the irregularly distributed     chert bands on the dolomite cliff. After a long-term weathering, these chert bands look like a huge boa.
