《徐霞客游记·滇游日记十三》
山巅与中部突起的山尖南北相对，上面有堆砌的石墙横界，这是元谋县的西界、大姚县的东界，就是武定府、姚安府的分壤处。
其巅与中突之尖，南北相对，上有石叠垣横界，是为元谋东界、大姚西界，即武定、姚安二府所分壤处也。
The mountain peak and the mountain top at the centre were opposite each other, with a stacked stone wall running across the top. This was the western boundary of Yuanyang County and the eastern boundary of Dayao County, the dividing line between Wuding Prefecture and Yaoan Prefecture.
