《徐霞客游记·滇游日记七》
原来西部的大山，往北走向的一支脉，从西南往东北横列，耸起屏障般的山峰最为高大，如同层层车盖向上簇拥；往南走向的一支脉，也是从西南往东北横列，但排排的峰峦逐渐下降，如同布慢向外斜挂；山势虽然北部高、南部低，而山脉走向其实是从南部往北部重叠，而且其中有一道陡峭的草木丛生的警沟，为通往山上的孔道，这是果马山；而往南往北的河流从这里分界。
盖西界大山，北向一支，自西南横列东北，起嶂最高，如重盖上拥；南向一支，亦自西南横列东北，排峦稍杀，如外幔斜骞，虽北高南下，而其脉实自南而北叠，而中悬一箐为丛薄，为中通之隙焉，是曰果马山；而南北之水由此分矣。
The original range of mountains to the west, a branch of the ones going northward, ran from the southwest to the northeast in a row, with its towering peaks resembling layers of car covers stacked upward. Another branch going southward also ran from the southwest to the northeast, but its peaks gradually descended, hanging outward like unfurled cloth. Although the mountains were taller in the north and lower in the south, the range actually overlapped from the south to the north, with a steep ravine covered with grass and plants as the path leading to the mountain. This was Mount Guomachong, and rivers flowing south and north separated from here.
