The Eureka Valley Sand Dunes are located in the southern part of Eureka Valley, in northern Inyo County in eastern California, in the southwestern United States. Although covering an area of only 3 square miles (8 km²), [roughly 1 mile by 3 miles], the dunes rise approximately 600 feet (180 m) above the surrounding valley floor, making them one of the highest dune fields in North America.
