Location
The dunes are located west of the Chocolate Mountains in Imperial County, and are crossed by Interstate Route 8 and State Route 78, which passes through the old train stop of Glamis at the eastern edge of the dune field. The northwestern end is located at 33°8′53″N 115°19′29″W / 33.14806°N 115.32472°W / 33.14806; -115.32472 about 11 mi (18 km) east of Calipatria, California, and the southeastern end is located at 32°41′4″N 114°46′7″W / 32.68444°N 114.76861°W / 32.68444; -114.76861 near Los Algodones in Mexico about 6 miles west of Yuma, Arizona. The dunes are also now separated at the southern end by agricultural land (see accompanying photo) from the much more extensive Gran Desierto de Altar, to which they once were linked as an extreme peripheral "finger". The only significant human-made structures in the area are the All-American Canal that cuts across the southern portion from west to east and the Coachella Canal on the western edge.
