棺材潭发育在白垩系官草湖组凝灰质砾岩中，海拔标高260m，呈长方形，潭长约25m，宽2-3m，深约3m，为流水沿节理裂隙面冲刷形成，流水正东方向。潭边发育小型壶穴。相传南宋末代皇帝宋帝昺（Bǐng）逃难至此处，曾御用此水，历代许多人也纷纷到此饮水，以求升官发财，财达运通，故而又名“官财潭”。

Guancai pool is developed in tuffaceous conglomerate of the Cretaceous Guancaohu Formation, 260m above the sea level, rectangular in shape, 25m long, 2-3m wide and 3m deep. It is formed by the water scouring along the joint and fracture plane in due east direction. Small potholes develop by the edge of the pool. According to the legend, the late emperor Zhao Bing of the Southern Song Dynasty fled to this place and ever used the water, then many people of all dynasties came to drink it one after another, to pray for a higher position and fortune, therefore, it is called Guancai (Position and wealth) pool.
