《徐霞客游记·滇游日记三十一》
本地人讲起，三十年前，山上都是大树巨竹，密蔽得没有空隙，中央有四个龙潭，深不可测，有脚步声传到波浪就腾涌而起，人不敢走近；后来有牧羊的，一声惊雷便震死了五六百只羊及几个牧羊人，连日连夜大火，大树深竹，被烧得了无孑遗，而龙潭也变成了陆地，今天山下有出水的洞穴，全是从山脚分引流出的。
土人言， 三十年前，其上皆大木巨竹，蒙蔽无隙，中有龙潭四，深莫能测，足声至则涌波而起，人莫敢近；后有牧羊者，一雷而震毙羊五六百及牧者数人，连日夜火，大树深篁，燎无孑遗，而潭亦成陆，今山下有出水之穴，俱从山根分逗云。 
Local people said that 30 years ago, there were big trees and giant bamboos on the mountain, densely covered, and there were four dragon pools in the center, which were unfathomable. When there was a sound of footsteps, the waves would rise, and people dared not go near; later there were herders The sheep was killed by a thunderbolt and several herders. The wildfire lasted for several days and nights. The big trees and deep bamboos were burnt without any trace, and the dragon pool also became land. Today, there are water-filled caves at the foot of the mountain, which are all diverted from the foot of the mountain.
