@tiogt2: This is the world's only fissure where the two banks belong to different geological eras. The left bank is composed of Triassic strata (200-240 million years old), while the right bank is composed of Permian strata (250-290 million years old). It's a breathtaking natural wonder. #TravelRecommendation #NaturalWonder #Fissure #AerialChina #AerialChina
