50 free Guadalupe Mountains National Park trivia questions with answers — geography quiz, new questions added Aug 2026.
This Guadalupe Mountains National Park trivia quiz covers the remote West Texas park where the highest point in the state rises out of the Chihuahuan Desert. Questions range across Guadalupe Peak and its odd summit pyramid, the great limestone prow of El Capitan, the Permian-age Capitan Reef the mountains are made of, McKittrick Canyon and its bigtooth maples, the gypsum dunes of the Salt Basin, and the black bears, elk and 16 kinds of bat that live there. The human story runs from the Mescalero Apache and the Buffalo Soldiers through the Butterfield Overland Mail's Pinery Station, the Frijole and Williams ranches, and Wallace Pratt, the Humble Oil geologist whose gift of McKittrick Canyon and whose house shaped like an oil tanker made the park possible in 1972. Difficulty runs from easy to expert and is marked on every question, so it works for a road-trip game on US 62/180 or a serious park-nerd challenge. Every answer was checked against Wikipedia or National Park Service pages and each question carries its citation. If you enjoy it, try our US National Parks quiz next.

Q 01Guadalupe Mountains National Park lies about 90 miles east of which Texas city?
El Paso
It sits hard against the New Mexico line in far West Texas, roughly 50 miles southwest of Carlsbad.
Q 02How high is Guadalupe Peak, the highest point in Texas?
8,751 feet
It rises more than 3,000 feet above the desert floor; the 8.4-mile round-trip trail is rated very strenuous.
Q 03What marks the summit of Guadalupe Peak?
A stainless steel pyramid
American Airlines erected it in 1958 for the centenary of the stagecoach mail line that passed south of the mountain; its three faces carry the airline's logo, a Postal Service tribute and a Boy Scouts compass.
Q 04Guadalupe Peak is also known by what alternative name?
Signal
The peak is about 50 miles southwest of Carlsbad, New Mexico, and the trail to the top climbs some 3,000 feet in 4.25 miles.
Q 05El Capitan, the range's southern tip and a landmark to travellers, looms over which highway at the park?
US 62/180
Its thousand-foot cliff is pure Capitan limestone, and its stark outline is one of the iconic images of the Trans-Pecos.
Q 06The Guadalupe Mountains are an exposed portion of what?
A Permian-age fossil reef
The Capitan Reef, built by tiny sea creatures around an inland sea, is now considered one of the best-preserved fossil reefs in the world.
Q 07The Capitan Reef ringed which vanished inland ocean during the Permian?
Delaware Sea
When its outlet silted up the sea evaporated, leaving layers of gypsum, halite and potash salts that buried the reef for 150 million years.
Q 08Unlike modern coral reefs, the Capitan Reef was built mainly by which organisms?
Sponges and algae
Tiny colonial bryozoans helped too, and encrusting organisms cemented the whole mass into rock; the end-Permian extinction wiped most of the builders out.
Q 09Roughly how long is the Capitan Reef Barrier, of which the Guadalupes are one exposed section?
350 miles
Other portions surface in the Apache and Glass Mountains; most of it still lies buried under the Permian Basin oilfields.
Q 10The Guadalupe Mountains lend their name to which subdivision of the Permian period?
The Guadalupian
The International Commission on Stratigraphy dates it to roughly 272 to 260 million years ago.
Q 11The dark, organic-rich basin sediments in front of the ancient reef eventually turned into what?
Oil and gas
That is why the Permian Basin around the park is one of the richest petroleum provinces on Earth.
Q 12In which year was Guadalupe Mountains National Park dedicated and opened to the public?
1972
Lyndon Johnson had signed the establishing act in 1966; Congress made 46,850 acres of the park wilderness in 1978.
Q 13Which president signed the act establishing Guadalupe Mountains National Park on October 15, 1966?
Lyndon B. Johnson
It came seven years after Wallace Pratt donated nearly 5,000 acres of his McKittrick Canyon ranch to the Park Service.
Q 21Which Apache band harvested agave in the Guadalupes and takes its name from that plant?
Mescalero
Mescalero means mescal-maker in Spanish; their agave roasting pits can still be found in the park.
Q 22Which Army regiment was sent to the Guadalupes after the Civil War to stop raids on the mail route?
9th Cavalry
These Buffalo Soldiers under Lt. H.B. Cushing destroyed two Apache camps in the winter of 1869.
Q 23The Pinery, whose ruins stand near the Pine Springs visitor center, served which stage line?
Butterfield Overland Mail
Built in 1858, it was the highest station on the 2,800-mile St. Louis to San Francisco route.
Q 14Wallace Pratt, who donated McKittrick Canyon, was what by profession?
Petroleum geologist
He was Humble Oil's first geologist in 1918 and proved that geology, not luck, found oil; Standard Oil later named a tanker after him.
Q 15Wallace Pratt's second house in the park, built to resemble an oil tanker, is known by what name?
Ship on the Desert
He and his wife, the suffragist Iris Calderhead, summered in the canyon until 1960.
Q 16The McKittrick Canyon Trail reaches Wallace Pratt's stone lodge after roughly how many miles?
2.4
The canyon is a day-use area with limited hours, reached by a 4.2-mile gated side road off the highway.
Q 17McKittrick Canyon is famous each autumn for the turning leaves of which tree?
Bigtooth maple
Oaks and ash join in, and the colour is all the more striking against the surrounding desert.
Q 18Which unusual tree with red bark that curls and peels off each year grows in the park's canyons?
Texas madrone
It grows scattered among yuccas, sotol and ocotillo in the lower canyon before the maples take over.
Q 19McKittrick Canyon is thought to be named after Felix McKittrick, who did what there in the 1870s?
Worked cattle
He was among the first European settlers in the range; the first permanent ranch house went up nearby in 1876.
Q 20What is the only significant surface water in the mostly limestone range?
McKittrick Creek
Rain vanishes into the porous rock, which is why the uplands have almost no streams and why great caves formed nearby.
Q 24How long did stagecoaches use the Pinery Station before the route moved south past Fort Davis?
Less than a year
The new road was better protected from Apache attacks; ten Guadalupe-route stations were abandoned and 16 added on the Fort Trail.
Q 25What meal did the Pinery Station famously serve to stage drivers and passengers?
Venison pie and baked beans
Passengers rode three abreast with knees interlocked, baggage on laps and mailbags under their feet, covering about 120 miles a day.
Q 26How thick were the limestone-and-adobe walls of the Pinery Station, built to withstand raids?
30 inches
They stood 11 feet high around a corral and a three-room station house; the site had been a military camp since 1849.
Q 27Which restored 1876 ranch in the park houses a museum and is the Smith Spring trailhead?
Frijole
It served as the region's community center and post office from 1916 to 1942 and is the most complete early ranch complex in the range.
Q 28Who built the first permanent ranch house in the Guadalupes in 1876?
The Rader brothers
Later occupants the Smiths called it Spring Hill Ranch and ran a truck farm; the complex joined the National Register in 1978.
Q 29In which year was the park's Williams Ranch House, reached only by a rough 4WD road, built?
1908
It is named for James Adolphus Williams, one of its inhabitants; a Van Horn judge later consolidated most local ranches into one spread.
Q 30The dunes on the park's west side are made of what?
Gypsum sand
They lie in the Salt Basin below the western escarpment, where a fault dropped the valley floor about 1,000 feet relative to El Capitan.
