The Development of a Typical RingShaped Cliff Danxia
These illustrations reveal how the distinctive landscape of the ring-shaped cliff Danxia was formed—the uplift of the Yunnan-guizhou Plateau and the mountains to its north created a stageshaped landform, and river turned into a waterfall when it met the edge of these stages. The waterfall eroded the relatively softer rocks, leaving the harder ones to form caves on the cliff. These caves, together with further erosion by the waterfall, collapsed the cliff walls, thus making a ring-shaped cliff appear. After years of polishing by the water, the cliff’s shape and appearance became stable, namely what we see today.
