the reed flute (or karst) cave in guilin, southern china, was carved out of the karst limestone mountains over 180 million years ago from an underground river and that has now settled into a lake. more than 70 ink inscriptions dating back to 792 ce can also be found inside the cave, which was left forgotten for a thousand years before being rediscovered in the 1940s by a group of refugees fleeing japanese troops. photos by james p. nelson, christian ortiz, jesse estes, adam allegro, filip m.a.
