ALGODONES DUNES, IMPERIAL COUNTY MAY 2008
Photographs by Michael Charters




Algodones Dunes is a large 45-mile long sand dune field located in the southwestern part of California near the Arizona border. To the east are the Chocolate Mountains. The dunes were apparently created by wind-blown sands from the ancient Lake Cahuilla. An upside-down V symbol next to the common name indicates a taxon that was new to me when I photographed it on this field trip.
