A Note on Asymmetrical Structures Caused by Differential Wind Erosion of a Damp, Sandy Forebeach

Richard W. Berry


Asymmetrical structures (5 to 10 mm high, 10 to 20 mm long, and 5 to 10 mm wide) were observed on a damp, sandy beach at Bahia de los Frailes, Territory of Baja California, Mexico. The structures were formed as a result of differential erosion by wind. They were elongated parallel to the wind with the steep slopes of each structure facing into the wind. Nonuniform compaction of sand grains along the beach is suggested as a fundamental reason for the development of the structures.
