《徐霞客游记·滇游日记三十八》
二里，山坞北面向西下坠成峡谷，路从高峰西北的山崖上走，绕过山湾，越过前突的山坡，三里多，向西北下到峡中，那下走的路非常陡峻，而且道路荒芜小径狭窄，怀疑不是通道。
二里，坞北坠峡西下，路从崇峰之西北崖行，盘其湾，越突坡，三里余，西北下峡中。其下甚峻，而路荒径窄，疑非通道。
After two miles, the mountain basin drops down to the west to form a canyon in the north. The path follows the cliffs northwest of the peak, rounds the mountain bend, and crosses the protruding hillside for three miles, descending into the canyon to the northwest. The path down is very steep, narrow, and overgrown, and I doubt that this is the way.
