Danxia landform carved by nature appears in a variety of shapes along Bingling Lake in Yongjing county. Danxia, literally meaning "red rocks", is a special landform formed from reddish sandstone that has eroded over time into a series of mountains surrounded by curvaceous cliffs and many unusual rock formations. A very peculiar feature of the danxia landscape is the development of numerous caves of various sizes and shapes. The caves tend to be shallow and isolated. [Yan Weijue/chinadaily.com.cn]
