found: Forbes Magazine WWW site, June 7, 2018:(Danxia; landform in China's Gansu Province; "formed by the erosion of red sandstone, forming isolated peaks and steep stratified outcrops. Its special geological structure, combined with long-term desert conditions, freeze-thaw peeling, and wind and water erosion gave rise to its present appearance. Geologists believe that Danxia topography is formed by folding of layered oceanic crust. Exposed slanting rock layers have different colors, textures, shapes, sizes, and patterns. The combination of differences in density and erosion create towering peaks, cave holes, and stone halls.")
