Yardangs in Lop Nur (3/7)

A yardang is a streamlined hill carved from bedrock or any consolidated or semi consolidated material by the dual action of wind abrasion, dust and sand, and deflation. Depending upon the winds and the composition of the weakly indurated deposits of silt and sand from which they are carved, yardangs may form very unusual shapes. (Photo/People's Daily Online)
