石柱是岩溶洞穴中由石笋和钟乳石相向生长，对接形成的柱状体。敢沫岩入口处石柱高约30m，直径约7m，蔚为壮观，形似凤凰展翅迎接前来游览的客人，故而得名凤凰迎宾。

The Stone pillar is a columnar body from the ceiling to the floor of a karst cave. It is formed when a stalactite and a stalagmite meet. At the entrance to Ganmoyan cave, the spectacular stone pillar looks like a phoenix spreading its wings to welcome guests, is about 30m high and 7m in diameter, hence the name “Phoenix Welcoming Guests”.
