《徐霞客游记·滇游日记三十三》
此峡的北边就是东山到了此地南边的尽头，南面就是东岭往西转，向西矗立在南香甸南边，成为江东山的北岭的地方。
其峡北即东山至此南尽，南即东岭之转西，西矗于南香甸南，为江东山北岭者也。
On the north side of this gorge is the end of Dongshan on this side. To the south, Dongling turns west, standing tall at the west end of Nanxiangdian and becoming the place where the north ridge of Jiangdongshan is.
