《徐霞客游记·滇游日记三十》
越过山脊往西行走在峡中，十分平坦，路南渐渐有山涧依傍在南面山崖下往西下流，路在山涧北边延伸。
逾脊西行峡中，甚平，路南渐有涧形依南崖西下，路行其北。
Cross the ridge and go west through the canyon, which is very flat. Gradually, there is a ravine on the south side of the road, flowing west under the south cliff, and the road extends to the north of the ravine.
