《徐霞客游记·滇游日记三十七》
北厢房的西头也有个洞，高处深处都是一丈五尺，也在洞口建了拱门，但朝向南方，在正洞的北隅，洞中则塑了山神像作为护法神。
北庑之西亦有洞，高深俱丈五尺，亦卷其门，而南向于正洞之北隅，其中则像山神以为护法者。
There was also a cave at the west end of the north wing, fifteen feet high and deep, with an arched entrance facing south at the north corner of the main cave, and a statue of a mountain god had been placed in the cave as a guardian deity.
