《徐霞客游记·滇游日记三十九》
山坡西边有壑谷盘绕在山中，由壑谷北边的山崖上走半里，环绕着上登它西边的山脊，约三里，由山脊向西南下走。
坡西有壑中盘，由壑之北崖半里，环陟其西脊，约三里，由脊西南下。
There is a gulf circling the mountain on the west side of the mountainside. Walk half a mile from the cliffs on the north side of the gulf, and circle around to climb its western ridge, about three miles, and go southwest from the ridge.
