50 free White Sands National Park trivia questions with answers — geography quiz, new questions added Aug 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
It sits in the Tularosa Basin about 15 miles southwest of the nearest town, and it is the state's most visited NPS site.
Q 02The park's white dunes are made of which mineral rather than ordinary quartz sand?
Gypsum
It is calcium sulphate, the stuff of plaster and drywall, left behind by Permian seas and washed down from the mountains.
Q 03What distinction do the park's dunes hold worldwide?
Largest gypsum dunefield on Earth
It holds some 4.5 billion tons of sand at an average depth of some 30 feet.
Q 04How tall are the tallest dunes in the park?
About 60 feet
They are biggest and fastest-moving on the western side and shrink to nothing at the eastern edge.
Q 05Roughly what share of the whole dunefield lies inside the park, with the rest on the missile range?
About 41%
The park protects about 115 of the 275 square miles; the other 160 lie to the north on Army land.
Q 06What kind of military installation completely surrounds the park?
An Army missile-testing range
Holloman Air Force Base sits just to the east, and the park closes for hours at a time during missile tests.
Q 07Which president designated White Sands a national monument on January 18, 1933?
Herbert Hoover
A local businessman had lobbied for a park but was told monument status would be easier; he became its first custodian.
Q 08In what year was White Sands redesignated a national park?
2019
The change rode inside that year's National Defense Authorization Act, along with land swaps with the missile range.
Q 09Fossilised human footprints at White Sands have been dated to roughly how long ago?
21,000 to 23,000 years
That is thousands of years before the accepted arrival of people in the Americas, and later dating of pollen and quartz backed it up.
Q 10Which Ice Age lake covered much of the Tularosa Basin, its dried bed leaving the Alkali Flat?
Lake Otero
At 1,600 square miles it was bigger than Rhode Island.
Q 11Which dry lakebed in the park's southwest corner periodically fills and evaporates to leave new crystals?
Lake Lucero
Rangers lead a hike there once a month in the cool season; it is inside the permit-only cooperative use area.
Q 12The mineral that crystallises out of the evaporating lake takes what form before wind grinds it to sand?
Selenite
Crystals on the Alkali Flat can reach three feet long before weathering breaks them down.
Q 13Roughly how many endemic species live only in this park, most of them moths?
At least 45
Forty are moths; the rest include the Apache pocket mouse, White Sands woodrat, bleached earless lizard and two camel crickets.
Q 21Which Apache leader's warriors fought the 9th Cavalry Buffalo Soldiers at the 1880 Battle of Hembrillo Basin?
Victorio
The Apaches were eventually forced onto the Mescalero reservation, which still keeps ties to the landscape.
Q 22Spanish colonists established trails in 1647 across the basin to reach what?
Salt pans
Salt was essential for processing silver ore in the mines of Durango, south of the border.
Q 23The 1854 'Magoffin Salt War' ended with what legal precedent?
Free public access to the deposits
James Magoffin had fatally wounded three Hispano salt gatherers from Doña Ana while trying to enforce his claim.
Q 14Why have several of the park's lizards, mice and insects evolved pale colouring?
To hide from predators on the white sand
The bleached earless lizard and little white whiptail are among the palest.
Q 15Which is the only fish species found in the park?
White Sands pupfish
It grows to only some 2 inches with silver scales and dark eyes.
Q 16Which ant found in the park is believed to have the most toxic insect venom in the world?
Maricopa harvester ant
A dozen stings could kill a 4.4-pound rat, and humans get up to four hours of intense pain.
Q 17Which small rodent in the park can leap up to 10 feet high when startled despite a 5-inch body?
Merriam's kangaroo rat
Black-tailed jackrabbits in the park can hit 40 mph.
Q 18Which bat, the park's most commonly seen, hunts most of its prey by walking on the ground?
Pallid bat
It roosts under the visitor centre's eaves in summer.
Q 19Which African antelope, released on the missile range for hunting, prompted a 67-mile fence around White Sands?
Oryx
With no predators they multiplied into the thousands; the NPS built the boundary fence in 1996 to keep them out.
Q 20Which Ice Age animals left fossil trackways on the old lakebed alongside human footprints?
Mammoths, ground sloths and camels
One set of human prints appears to show people stalking a sloth; wind exposes the fragile tracks and erases them within a couple of years.
Q 24Which senator, later disgraced in Teapot Dome, pushed an 'All-Year National Park' for the basin from 1912 to 1922?
Albert B. Fall
NPS director Stephen Mather panned the plan's 'disjointed boundaries, lack of spectacular scenery, and questionable usage'.
Q 25Which businessman promoted the dunes in the 1920s and became the monument's first custodian?
Tom Charles
He also pushed through the improved state road that became U.S. 70.
Q 26Which New Deal agency built the park's original adobe visitor centre and seven other buildings from 1936 to 1938?
Works Progress Administration
Architects Lyle Bennett and Robert Albers designed them; the district joined the National Register in 1988.
Q 27Villagers at Tularosa and La Luz in the 1860s mixed dunefield sand with water to make what for their homes?
White plaster for adobe walls
Heated to 300 F, the dune mineral becomes plaster, which is also why prehistoric hearths in the dunes are cemented in place.
Q 28Which family ranched on the shore of the dry lake that now carries their name from 1897?
The Luceros
Their stock pens, well and fallen windmill can still be seen on the monthly ranger tour.
