How old is the Yellow River Gallery now?

The Yellow River Gallery was unknown to the world at first and has been sleeping silently on the cliff of this canyon. In 2000, Mr. Chen Baosheng, a professor of Shaanxi Academy of Fine Arts and a national first-class photographer, drifted by wooden boat from Jiaxian to Qiaokou, passing by, and accidentally discovered this miracle. Since then, the Yellow River Nature Gallery has been gradually known by the world. This pure natural masterpiece of art brings together many paintings, architecture, sculpture, calligraphy and so on. Mr. Wu Guanzhong, a famous Chinese painter, visited the scene many times and spoke highly of this spectacle. He said that the relief murals on the stone walls of the Yellow River have high artistic appreciation value.

In recent years, with the rise of tourism, this rare natural wonder in China has attracted a large number of domestic and foreign tourists, including a large number of photographers, art lovers and some geological experts. It is no exaggeration for a tourist from afar to say: "The Yellow River Gallery is no less than the peculiar antelope canyon formed by flash floods in Arizona, USA." Another tourist praised: "This is the most beautiful natural scenery in the Yellow River Basin." ...

According to experts' research, the geological relics of the Yellow River water erosion landform were formed in the geological movement about 200 million years ago. It is a natural cliff landform formed by groundwater dissolution and river erosion in Triassic thick sandstone. Of course, the formation of relief also plays an important role in wind erosion and illumination.
