GREAT SAND DUNES NATIONAL MONUMENT

Beautiful photograph of the Sand Dunes.
Colorado Sand Dunes The Great Sand Dunes are located about 10 miles northeast of Alamoso, Colorado. The dunes are continuously deposited by winds blowing over the Sangre De Cristo Mountains. The highest dune stands over 700 ft above the San Luis Valley floor. The valley itself lies at an altitude of about 8000 ft above sea level. A climb to the top of the dunes can be quite strenuous because of the high altitude and loose sand. The sand can also reach a temperature of 135 degrees.
