《徐霞客游记·黔游日记六》
由山脊往北下山，极深，而道路荒芜；由山脊上往西转，沿威山北峰的半腰上西行，道路荒芜可石阶还在。
由脊北下，甚深而路芜；由脊西转，循山北峰之半西行，路芜而磴在。
It was very deep to go down the mountain from the mountain ridge to the north, and the road was wasted; from the mountain ridge to the west, we walked along the middle of the north peak of Mt. Wei to the west, and the road was wasted, but stone steps were still there.
