Great Sand Dunes National Park and Preserve is in the San Luis Valley of south-central Colorado at an elevation of 8,175 feet. The dunes lie on the eastern edge of the valley at the base of the Sangre de Cristo Range. The dunefield is part of the nearly 150,000 total acres of the park and preserve that also protects alpine lakes, tundra, six peaks over 13,000 feet, ancient spruce and pine forests, large stands of aspen and cottonwood, grasslands, and wetlands. The park is part of a fragile, dynamic system that influences and sustains the tallest dunes in North America.

President Herbert Hoover established the park unit as a national monument by presidential proclamation on March 17, 1932 through the Antiquities Act. The Works Progress Administration constructed the Superintendent’s Residence, now listed on the National Register of Historic Places. But otherwise, GRSA did not see a great deal of development during the New Deal. Park development did not occur in earnest until Mission 66.

During this period, the NPS was able to construct a Visitor Center, the Pinon Flat Campground (88 sites), a picnic area, five comfort stations, six single family residences and a triplex, while also building or improving roads and trails through the park. The Visitor Center shows the motivation of the Western Office of Design and Construction to configure designs to corresponding regions using principles of “regional modernism.” Built in the Pueblo Revival style, the Visitor Center mimics adobe construction through modern materials and forms blended with traditional materials and forms seen during the CCC-era in Cecil Doty’s work.

Following Mission 66, Congress designated nearly 91% of the monument as wilderness in 1976, which certainly limited the park’s ability to further develop visitor and administrative facilities. GRSA became a national park and preserve in 2000, which also included a transfer of land from the Rio Grande National Forest.

The dunes have long stood as a landmark for travelers from ancient North Americans to Southern Ute, Jicarilla Apaches, Navajos, early explorers, gold miners, homesteaders, ranchers, farmers and migrant field workers, to you - today's park visitor.
