49 free White Sands National Park trivia questions with answers — geography quiz, new questions added Sep 2026.
This White Sands National Park trivia quiz covers the dazzling gypsum dunefield in southern New Mexico's Tularosa Basin, the largest of its kind on Earth, ringed on every side by an Army missile range. It ranges across how the sand forms from evaporating Lake Lucero, the dome, barchan and parabolic dunes, the ghost-white lizards, mice and moths that evolved there, the Ice Age footprints that may be the oldest human tracks in the Americas, and the sledding, sunset strolls and full-moon hikes that draw 600,000 visitors a year. There is plenty of history too: the Apache and the Buffalo Soldiers, the Spanish salt trails, the Magoffin Salt War, Albert Fall's doomed 'All-Year National Park', Herbert Hoover's 1933 monument, the WPA adobe buildings, missiles falling in the dunes, the oryx fence, the Hollywood shoots, and the 2019 law that finally made it a national park. Questions run from easy to expert with the difficulty shown on each one, so it works for a Dunes Drive car game or a serious park-nerd challenge. Every answer was checked against a reference page and each question carries its citation. If you enjoy it, try our Carlsbad Caverns, Great Sand Dunes and US National Parks quizzes next.

Q 01White Sands National Park is in which U.S. state?
New Mexico
New Mexico: the dunes fill part of the Tularosa Basin, a desert bowl whose outlet to the sea was blocked long ago, so the mineral washed down from the mountains stayed put instead of draining away.
Q 02The dunes of White Sands National Park are made of which mineral, rather than ordinary quartz sand?
Gypsum
Gypsum dissolves in water, so rain and snowmelt carried it down from the mountains in solution. Trapped in the basin, it crystallised as the lakes dried, and the wind ground the crystals into sand.
Q 03White Sands National Park lies in which desert, also home to Big Bend National Park?
Chihuahuan Desert
Chihuahuan Desert: a high desert, and no gentle place. The park has recorded both 111 degrees Fahrenheit in summer and a winter night of minus 25.
Q 04In which direction are the dunes of White Sands slowly marching, driven by the prevailing wind?
Northeast
Northeast: winds from the southwest drive them on, fastest at the bare upwind edge, while the plant-covered dunes on the far side barely move at all.
Q 05In 1982, which space shuttle made the programme's only landing at White Sands?
Columbia
Columbia came down on a desert runway beside the dunes because its planned landing site in California was flooded. White dust from the strip kept turning up inside the orbiter for the rest of its career.
Q 06The missile range that completely surrounds White Sands National Park is run by which military branch?
The Army
The Army runs White Sands Missile Range, and the park lives by its timetable: when a test is on, the only road into the dunes can be shut for up to three hours.
Q 07Which president, in his final weeks in office in January 1933, made White Sands a national monument?
Herbert Hoover
Herbert Hoover signed the proclamation under the Antiquities Act six weeks before leaving office. Local boosters had wanted a full national park but were advised a monument would be far easier to get.
Q 08White Sands became a national park in 2019 through a provision tucked inside what kind of bill?
A defence bill
A defence bill: the change rode inside the annual National Defense Authorization Act, which also swapped land between the park and the missile range that surrounds it.
Q 09Footprints at White Sands, dated by researchers to over 21,000 years ago, would overturn the accepted date of what?
People reaching the Americas
People reaching the Americas: the accepted date had been 13,000 to 16,000 years ago. Critics argued the seeds used for dating could read too old, but 2023 tests on pollen and quartz grains gave the same answer.
Q 10Which Ice Age lake once covered much of the Tularosa Basin, leaving the flats that feed White Sands' dunes?
Lake Otero
Lake Otero dried up as the Ice Age ended, and its bed became the Alkali Flat: the crystal-crusted plain that the wind has been grinding into dunes ever since.
Q 11Which dry lakebed in White Sands' southwest corner still floods now and then, leaving fresh crystals as it dries?
Lake Lucero
Lake Lucero is often called the birthplace of the dunes, because the crystals that form as it dries are what the wind grinds into sand. Rangers lead a monthly hike down to it in the cooler months.
Q 12Before the wind grinds it into White Sands' dunes, the mineral forms which crystals on the lakebed?
Selenite
Selenite crystals can grow as long as a forearm on the Alkali Flat; wind and water then break them into ever smaller pieces until the grains are fine enough to blow away as sand.
Q 13Most of the 45 or so species found only at White Sands belong to which group of animals?
Moths
Q 21In 1880, Victorio's Apache warriors fought which famous cavalrymen at Hembrillo Basin, beside today's White Sands?
The Buffalo Soldiers
The Buffalo Soldiers of the 9th Cavalry fought one of the largest battles of Victorio's war there. Archaeologists have since plotted more than 800 spent cartridges from the fight and traced them to 147 rifles and 39 pistols.
Q 22In 1854 an El Paso merchant's armed posse fought Rio Grande villagers over which Tularosa Basin resource?
Salt pans
Salt pans: James Magoffin claimed the deposits and wanted payment for the salt, so when villagers set out to gather it without paying, he went after them with an armed posse.
Q 23What lies only a few feet beneath the dry surface of White Sands, helping to hold the dunes in place?
Moths: about 40 species live nowhere else, and not one of them was known to science before 2007. Like the park's pale lizards and mice, most of them are white.
Q 14Why have several of White Sands' lizards, mice and insects evolved pale colouring?
To hide from predators
To hide from predators: darker animals stood out on the white dunes and were picked off first, so in about 7,000 years their descendants have turned far paler than relatives living a few miles away.
Q 15The only fish found in White Sands National Park, barely two inches long, is what kind of fish?
A pupfish
A pupfish: the White Sands pupfish lives nowhere else on Earth, a survivor of the basin's vanished Ice Age lake that copes with spring water ranging from fresh to saltier than the sea.
Q 16Which ant found at White Sands is believed to have the most toxic venom of any insect?
Maricopa harvester ant
Maricopa harvester ant venom tested about 20 times as toxic as a honeybee's in mice, yet the horned lizards that eat these ants shrug off doses more than a thousand times larger.
Q 17Which White Sands rodent has a tail longer than its head and body together?
Merriam's kangaroo rat
Merriam's kangaroo rat hops on long hind legs and needs that tail for balance, swinging it like a rudder to change direction suddenly when a hunter closes in.
Q 18Which bat, the most commonly seen at White Sands, finds most of its prey by walking on the ground?
Pallid bat
Pallid bat: its outsized ears pick up the footsteps of scorpions, centipedes and crickets, and in summer it roosts under the eaves of the visitor centre.
Q 19Which African antelope, released nearby for hunting, led White Sands to build a 67-mile boundary fence?
Oryx
Oryx bred from Kalahari stock were set loose from 1969 for sport hunting; with no natural check on their numbers, fewer than a hundred became thousands, and the park fenced itself off in 1996.
Q 20Which Ice Age animals left fossil trackways at White Sands alongside human footprints?
Mammoths, ground sloths and camels
Mammoths, ground sloths and camels all crossed the muddy lakeshore, and one trail appears to show people stalking a sloth, their footprints pressed inside its own.
Groundwater
Groundwater: rain and snowmelt from the mountains collect in the basin with nowhere to go, so the sand is damp just below the surface. Dry it out, and the wind could carry the dunes away.
Q 24Which figure of the Teapot Dome scandal had earlier pushed for an 'All-Year National Park' taking in part of White Sands?
Albert B. Fall
Albert B. Fall owned a ranch on the basin's edge. The Park Service's own director panned his plan's 'disjointed boundaries' and 'lack of spectacular scenery', and the bill failed after park and Indian-rights groups campaigned against it.
Q 25The mineral in White Sands' dunes was first laid down, over 250 million years ago, on the floor of what?
A shallow sea
A shallow sea, rising and falling while the continents were joined as Pangaea. Later upheavals lifted its bed into the mountains around the basin, and rain has been washing the mineral back down ever since.
Q 26Which New Deal agency is credited with building White Sands' adobe visitor centre in the 1930s?
Works Progress Administration
Works Progress Administration crews built it of sun-dried mud brick between 1936 and 1938, which is why it needs constant care: once the stucco skin cracks, wind and rain soon eat the adobe beneath.
Q 27Prehistoric campfires in White Sands' dunes survive as hard mounds because the heat turned the sand into what?
Plaster
Plaster: at about 300 degrees Fahrenheit the dunes' mineral becomes plaster of Paris, which set hard with the next damp spell and cemented each hearth in place for thousands of years.
Q 28Tracks of which extinct Ice Age animal were found at White Sands beside seeds over 18,000 years old?
Dire wolf
Dire wolf: heavier than a gray wolf and with a stronger bite, it probably hunted in packs, which let it bring down prey far bigger than itself.
Q 29Which 2007 blockbuster shot some of its desert scenes among the dunes of White Sands?
Transformers
Transformers filmed among the dunes while Holloman Air Force Base, right next door, stood in for the film's American base in Qatar.
Q 30Which Clint Eastwood western shot scenes on the dunes of White Sands?
Hang 'Em High
Hang 'Em High is set in Oklahoma Territory, but the crew never went near it: they filmed around Las Cruces in the summer of 1967 and used the white dunes for extra scenes.
