50 free Kobuk Valley National Park trivia questions with answers — geography quiz, new questions added Aug 2026.
This Kobuk Valley National Park trivia quiz covers the roadless, trail-less park 25 miles north of the Arctic Circle in northwest Alaska, where the Great Kobuk Sand Dunes rise a hundred feet out of the tundra and the Western Arctic caribou herd swims the Kobuk River twice a year. Questions cover the geography of the valley between the Baird and Waring mountains, the dunes and why NASA studies them, the midnight sun, the sheefish and salmon, and the wolves, bears and Dall sheep that share the valley with the caribou. The human story runs 12,500 years, from the Paleo-Arctic hunters at Onion Portage through nine cultural layers dug by archaeologist Louis Giddings, to the Inupiat who still hunt caribou at the crossing, the 1898 Kobuk River Stampede that turned out to be a hoax, Jimmy Carter's 1978 monument and the 1980 ANILCA park, and the headquarters in Kotzebue shared with two other Arctic parklands. Difficulty runs from easy to expert and is marked on every question, so it works for a bush-plane game or a serious park-nerd challenge. Every answer was checked against Wikipedia and each question carries its citation. If you enjoy it, try our US National Parks and Katmai quizzes next.

Q 01Kobuk Valley National Park lies about 25 miles north of what line?
The Arctic Circle
The sun never sets there for over a month in early summer and shows for only about an hour and a half on the winter solstice.
Q 02What surprising feature was the park created in 1980 to preserve, along with caribou migration routes?
Sand dunes
The Great Kobuk Sand Dunes are the largest active Arctic dune field in North America.
Q 03How tall are the Great Kobuk Dunes?
About 100 feet
Two smaller fields, the Little Kobuk and Hunt River dunes, lie nearby, all on the south side of the Kobuk River.
Q 04NASA has funded study of the Great Kobuk Dunes as an analog for what?
Polar sand seas on Mars
Glacial outwash and strong winds built the dunes after the Pleistocene ice retreated; forest and tundra have since buried most of the original 200,000 acres.
Q 05Roughly how much area do the park's active dune fields still cover?
About 20,500 acres
Right after the glaciers retreated the dunes covered as much as 200,000 acres; most has since been hidden under vegetation.
Q 06Roughly how many caribou belong to the Western Arctic herd that migrates through the park?
400,000
They cross the Kobuk River twice a year between wintering and calving grounds, a crossing central to Inupiaq subsistence hunting.
Q 07Where does the caribou herd spend the summer calving season?
North of the Baird Mountains
The wintering grounds lie south of the valley's lower southern range, so the herd's river crossing happens twice a year.
Q 08How big is Kobuk Valley National Park?
About 1.75 million acres, a bit larger than Delaware
About 81,000 acres inside it belong to Native corporations and the state, and a large tract south of the river is designated wilderness.
Q 09How many designated trails and roads does the park have?
None
Visitors bring all their own gear for backcountry travel and arrive by chartered air taxi from Nome, Bettles or the headquarters town.
Q 10Which town on the Bering Sea coast, about 100 miles west, hosts the park's headquarters?
Kotzebue
The Northwest Arctic Heritage Center there also serves Cape Krusenstern National Monument and Noatak National Preserve, run together as the Western Arctic National Parklands.
Q 11Kobuk Valley is managed with which two other units as the Western Arctic National Parklands?
Cape Krusenstern and Noatak
A single superintendent runs all three from the same building.
Q 12Which national park and preserve lies 32 miles east of Kobuk Valley?
Gates of the Arctic
Kobuk Valley sits between the Selawik National Wildlife Refuge and the Noatak National Preserve, over 75 river miles from the Chukchi Sea.
Q 13The park's northern boundary follows the crest of which range, the western end of the Brooks Range?
Baird Mountains
Q 21What is the National Historic Landmark archaeological site at a major caribou crossing on the Kobuk?
Onion Portage
Its deep layers hold nine cultural complexes from about 6500 BC to AD 1700 and anchor the cultural chronology of the Arctic.
Q 22How many cultural complexes are documented at the park's famous archaeological site?
Nine
They span roughly 6500 BC to AD 1700 at a site that has been a National Historic Landmark since 1978.
Q 23Which pioneering Arctic archaeologist identified Cape Krusenstern's great stratified site in 1940?
J. Louis Giddings
His cabin at the site is preserved by the Park Service; he also began the science of subarctic tree-ring dating along the Kobuk.
They were named for a 19th-century scientist; a lower range closes the ring to the south.
Q 14The park's northern range is named after Spencer Baird, secretary of which institution?
The Smithsonian
They cover about 5,600 square miles between the Kobuk and Noatak rivers, roughly 60 miles northeast of the headquarters town.
Q 15Which shorter range forms the southern rim of the Kobuk Valley?
Waring Mountains
The park boundary runs along its height of land, enclosing the valley in a ring with the Bairds to the north.
Q 16Which stretch of the Kobuk River lies inside the park?
The middle two-thirds, from above Kiana to below Ambler
Major tributaries like the Salmon and Hunt rivers are included too; the valley floor is mostly glacial drift.
Q 17What does the Kobuk's Inupiaq name, Kuuvak, mean?
Great water
It was first written down as Kowuk in 1850, and a Navy lieutenant later tried to rename it Putnam for a lost officer.
Q 18Roughly how long is the Kobuk River?
280 miles
It rises in the Endicott Mountains, not in Walker Lake as commonly assumed, and empties into Hotham Inlet.
Q 19Which large predatory whitefish, prized in the Kobuk, spawns in the river's upper reaches each autumn?
Sheefish
Chinook, chum, pink and sockeye salmon, Arctic char, lake trout and three kinds of whitefish also swim the park's waters.
Q 20Human habitation in the Kobuk Valley is believed to go back at least how long?
12,500 years
The first arrivals were Paleo-Arctic hunters who took caribou at a river crossing; the valley was abandoned and resettled several times since.
Q 24Which Native regional group holds the park's famous archaeological site as an inholding?
NANA
About 81,000 acres inside the park belong to Native corporations and the State of Alaska.
Q 25Which Native people live in the Kobuk valley, subsisting on its caribou and fish?
Inupiat
Their ancestors the Akunirmiut and Kuuvaum Kangiamirnuit left the valley in the mid-19th century when caribou declined; descendants are the Kuuvangmiit.
Q 26Arctic Small Tool people arrived in the valley some 4,000 years ago and departed roughly when?
1,500 to 1,000 years back
The valley then stood empty until new people arrived around AD 1200, documented at the Ahteut site 25 miles downriver.
Q 27What did Native people tell the roughly 2,000 prospectors who arrived for the 1898 Kobuk River Stampede?
That the gold reports were a scam
Only about 800 went upriver and found little or nothing; some 32 miners' camps from 1899-1900 have yet to be located.
Q 28Roughly how many prospectors' camps were set up in the park area during the brief gold rush of 1899-1900?
32
Surveys have found debris from the miners' boats but not the camps themselves.
Q 29Which president first protected Kobuk Valley as a national monument on December 1, 1978?
Jimmy Carter
He used the Antiquities Act while the Alaska lands bill was stuck in Congress; ANILCA followed on December 2, 1980.
Q 30Unlike many Alaska park units, Kobuk Valley has no national preserve; what does that mean for hunters?
Only local subsistence take is allowed
A preserve designation would have opened it to sport hunting; the whole park is national park land.
