The glacial moraine ice water accumulation layer (Q 1fgl) originated from the main water vein of the central park of Longmenshan National Geopark, with an altitude of 4,985 meters. It was formed by the natural infiltration and mineralization of the glacial drift gravel geological layer in Shan Yu in 16 years, which is very similar to the formation of Evian mineral water in Alps. Its surrounding area of 300 square kilometers is listed as a natural mineral water reserve during the Ice Age. It's just a brand promotion method, slogan and the like.
