national monument in New Mexico, United States

White Sands National Monument is a United States National Monument that is in the southeastern region of the state of New Mexico. The monument contains the world's largest gypsum sand dune field—275 sq mi (710 km2) of fine white sand, formed by the prevailing winds into large ridge-like dunes.

White Sands became a national monument on January 18, 1933 by order of President Herbert Hoover. Efforts to preserve the area's brilliant gypsum dunes had begun in the late 1800s, but it was the enthusiasm of local booster Tom Charles that finally led to the park's creation. In his words "gypsum may be divided into two classes - Commercial and Inspirational. The former everybody has, but as for recreational gypsum, we have it all. No place else in the world do you find these alabaster dunes with the beauty and splendor of the Great White Sands".

The park's creation coincided with the Great Depression, which was in some ways fortuitous due to the Roosevelt administration's focus on public works. WPA funds were used to improve many park areas and White Sands benefited by achieving a full measure of development within just a few years of opening. In its first year the park attracted 12,000 people, and today as many as 600,000 people visit the park annually.


The obvious natural feature of this monument is the pure gypsum dunes, but perhaps less obvious are the sources of the dunes, Lake Lucero and Alkali Flat. These two areas are the result of the gradual drying of an extensive Pleistocene lake that was rich in the mineral gypsum, with the dunes being the result of weathering and wind transport of these exposed surfaces.

The translucent golden-yellow crystals of selenite (gypsum) grow in saturated mud beneath the lake's remains. When exposed on the surface, these crystals are subject to weathering and erosion and may eventually become gypsum powder and sand grains, which can be carried by winds as dust or sand storms to become the white sands of White Sands National Monument.

Flora and faunaEdit

Most of the animals of White Sands have developed nocturnal habits to escape predators and the desert heat. In addition, due to the white sands some animals have evolved lighter coloration; there are forms of white reptiles, mammals, and invertebrates that blend with their white background (you probably won't see them unless they move). However, of the 44 species of mammals, 26 species of reptiles, 6 species of amphibians and nearly 100 families of insects recorded on the monument, the vast majority have normal coloration. Lizards can be readily observed in the interdunal areas where vegetation can be found for shade and protection. The park's mammals are primarily noctournal, so are not as easily observed. The light-colored amphibian, the spadefoot toad, only ventures from underground following thunderstorms when water is available for breeding and egg-laying in the pools of rainwater, where tadpoles quickly develop into adults and burrow into the moist sand, where they await the next season's storms.


Thunderstorms are common during the summer

The Tularosa Basin, a high desert area, averaging 4,000 feet (1200+ meters) in elevation, is subject to harsh, and sometimes rapidly changing climatic conditions. Summers are hot, with high temperatures averaging 95°F. (35°C.) in July and August. Winters are relatively mild, but night time temperatures often go below freezing (0°C.) and cold spells can send the mercury below zero (0°F / -17°C). The lowest recorded temperature is -25°F (-32°C). Snowfall is infrequent, but heavy snows have occurred on occasion. Precipitation averages about 8 inches (20 cm.) per year, with most falling during summer thunderstorms, often accompanied by lightning and hail.

Wind is the dominant climatic factor, especially from February through May. The prevailing southwesterly winds blow unimpeded across the desert and at times reach gale force. Wind storms can last for days in the spring. This is the time of the greatest dune movement, when living conditions for dune animal and plant communities become extremely harsh.

Get aroundEdit

By carEdit

An eight-mile scenic drive leads from the Visitor Center into the heart of the dunes. Wayside exhibits at pullouts along the drive provide information about the natural history of the park. Driving on the dunes is not allowed.

By bikeEdit

The dunes drive is an easy ride for individuals on bike. During full moons the park service offers reservation-only full moon bike rides, during which the drive is opened after-hours to bicycles. A special use fee of $5 is charged. Reservations can be made by calling +1 575 679-2599 (ext 111).


The sands with mountains in the backdrop
  • Wildflowers. From mid-April to mid-June desert wildflowers can be often be seen in bloom. The claret cup cacti bloom from late April through mid-May, while cholla cacti start blooming in mid-May. Some wildflowers bloom in Fall, usually from mid-August until as late as November.
  • White Sands Hot Air Balloon Invitational. This annual balloon festival sees numerous balloons rising over the monument.



Visitors are free to roam over any area within the park, but should avoid walking on the cryptobiotic crusts of the inter-dune areas. Entering the White Sands Missile Range is not allowed, so be aware of your location. Marked trails include:

  • Playa Trail. (0.2 mile, 0.3 km round-trip). A very short trail to a dried lakebed.
  • Big Dune Trail. (1 mile, 1.6 km round-trip). A self-guided nature trail.
  • Interdune Boardwalk. (0.4 mile, 0.6 km round-trip). A wheelchair-accessible nature trail.
  • Alkali Flat Trail. (4.5 mile, 7.2 km round-trip). A backcountry trail through the heart of the dunes. This trail is marked by posts with orange tape on them and may be difficult to follow for inexperienced hikers.

In addition, there is a monthly ranger-led hike to Lake Lucero (located in the Missile Range). The cost is $3 per person, and the round-trip takes three hours. Reservations are required and can be made by calling +1 505 479-6124 or +1 505 679-2599. The tour schedule is posted online, and is also available from the visitor center.


Crest of a dune

Some of the dunes are tall and steep enough to provide a good ride on a plastic tobaggan or sled. While some visitors attempt sledding on everything from carboard boxes to garbage bags, you'll want to bring your own sled for the best experience.


During the summer and early Fall the park service has Friday Night Star Talks on most Fridays.


Dune photography is best in the morning and evening when the sun is low on the horizon, producing interesting shadows on the dunes. Camera meters may be fooled by the white sand, so it is a good idea to meter slightly higher than what is reported by the light meter to avoid having the sands appear grey.


The gift shop at the visitor center offers books, maps, posters, videotapes and other souvenir items for purchase. Gas and supplies must be purchased outside of the park.


Light snacks and beverages are available in the visitor center gift shop, but there are no restaurants in the park. The nearby town of Alamogordo, 15 miles east of the park, has several restaurants available.


Water is available outside of the visitor center. Alcohol is prohibited within the park at certain times of the year; check at the Visitor Center for specific restrictions.



There is no lodging within the monument, but the town of Alamogordo, located 15 miles east of the park, has several hotels.


There are no organized campgrounds within the monument, but backcountry camping is available. Public and private campgrounds located near the park include Alamogordo (15 miles northeast), Las Cruces (52 miles southwest), Oliver Lee Memorial State Park (22 miles from park on highway 54, south) and at Aguirre Springs, a Bureau of Land Management (BLM) recreation area (35 miles southwest).


White Sands National Monument offers a primitive backcountry campsite located about one mile from the scenic drive. The trailhead to this campsite is 6 miles from the visitor center. The campsite is primitive with no water or toilet facilities. No ground fires are permitted, and visitors must pack out all trash and biological waste.

A few permits are required for backcountry use, and can be obtained on a first-come, first-served (no reservations) basis for $3 per person at the visitor center between 8AM and 4PM. Note that during testing at White Sands Missile Range the backcountry is closed and no permits are issued. Since missile tests are subject to change, please call the park the day before you plan to use the campsite to verify that the site will be available that night.

Stay safeEdit

While hiking on the dunes, be aware of your location as it is easy to become disoriented. Watch the weather, as sandstorms can reduce visibility and make it nearly impossible to find your way. Heat-related issues are also a concern; carry water with you, and drink at least a gallon of water per day on hot days. Sunscreen is a must.

When driving on the park roads follow speed limits, use turnouts, and lock your vehicle when not attended.

Go nextEdit

  • White Sands Missile Range, known locally as WSMR (and often pronounced "whiz-murr"), is nearby, with an interesting museum that covers some of the area's history and examples of some of the rockets and missiles that have been launched there. Generally open 10AM-3PM or 8AM-4PM, but call +1 575 678-8824 to verify hours; as it is on the territory of the Air Force base, closures or restrictions due to security concerns are possible.
  • 1 Trinity Site (arrive north on I-25, east on NM 380, enter at Stallion Gate). Site of the first nuclear bomb explosion, now a National Historic Landmark, in the remote area at the north of the range where the first atomic bomb was tested. Public tours, held twice a year on the first Saturday in April and October from 8AM-2PM, are a sobering experience (although not a hazardous one -- radiation levels at the site are generally back down to natural background). Free.
  • Continuing on the space/science theme, the New Mexico Museum of Space History in Alamogordo is worth a visit; the International Space Hall of Fame and a piece of lunar rock are among the attractions.
