《徐霞客游记·滇游日记三十三》
所谓的北峰，从大厂分支向西南下延，就是南香甸东突的山峰，我今天所走的路，沿着它的南垂向东而去，它的东南垂也是到了这里就完了。
所谓北峰者，从大厂分支西南下，即南香甸东突之峰，余今所行路，循其南垂向东者也，其东南垂亦至是而尽。
The so-called north peak branches out from Dachang to the southwest, which is the peak that protrudes east from Nanxiangdian, the road I walked today, going east along its south slope, its southeast slope also ends here.
