当时，探险队对一处名为天悬天坑的地方进行探测。该天坑深130米，宽约100米，四周皆为垂直的悬崖绝壁，坑内瀑布飞降，险峻异常。坑沿长着许多枫树，枫叶在金秋时节灿若云霞，与幽幽深谷形成鲜明对比。利用SRT（洞穴单绳）技术，探险队员下降到坑底，在底部斜坡灌木丛里发现了一只飞猫。[视觉中国 向航 摄]
The team are exploring the "Heavenly Huge Cave" when they find the flying squirrel. The cave has a depth of 130 meters and is 100 meters wide, with cliffs surrounding it and a waterfall that pours down to the bottom. The leaves of a maple tree are turning a glowing golden color, forming a sharp contrast with the serene darkness in the cave. [Photo/VCG]
