《徐霞客游记·滇游日记五》
往南看则分支山脉走向垂直，近处豁然开阔，远看重山环绕，这是和独木桥一带的众山遥相连带而往下聚集的山脉。
其南则支条直走，近界既豁，远巚前环，此独木诸所遥带而下泄者。
Looking south, the subsidiary mountain range is vertical and open close by, surrounded by tall mountains from afar. This mountains range is connected with the one at Dumuzhu Bridge area and extends downtrend.
