White Sands National Monument, New Mexico U. S. A.
White Sands National Monument is located in south central New Mexico. This national monument contains a vast area of snow white dunes that are not really sand but gypsom. The well marked hikeing trails course through the spectacular dunes. Dispersed through the dunes are many interesting plants which provide a stark contrast to the dunes. It was at this location that I recored the highest spot meter reading that I have ever encountered.
