Denali
Denali has the only sled dog kennel in the National Park Service, and its human and canine rangers have worked together since 1922 to care for the park’s wilderness by dog team.

The words
Alaska Range
This 600-mile (966 km) arc of mountains runs from the Canadian border to the Alaska Peninsula. Its highest stretch, crowned by North America’s tallest peak, lies within the park, where the Park Service likens the range to a “spiny backbone.”
Did you know?
The range is still being pushed up. The Pacific Plate, diving beneath Alaska and driving that uplift, creeps north about as fast as fingernails grow.

Dall Sheep
These white wild sheep feed and rest on the park’s high ridges and steep slopes, using crags to escape predators. The Park Service calls their protection the “primary driving force” behind the park’s creation in 1917, after Charles Sheldon lobbied Congress.
Did you know?
Each spring, Dall sheep often travel many miles to mineral licks, where they eat the soil itself.

Denali
From Koyukon Athabascan Deenaalee, “the tall one,” per linguist James Kari; Hudson Stuck’s 1914 book gives “the great one.”
Created in 1917 as Mount McKinley National Park to protect wildlife, the park was tripled in size and renamed Denali National Park and Preserve in 1980. It kept that name when the peak’s official name changed in 2025, the Park Service reports.
Did you know?
In 1975 the State of Alaska asked the U.S. Board on Geographic Names to make Denali the peak’s official name. Ohio’s congressional delegation, from McKinley’s home state, blocked the change for the next four decades.

Eielson
The visitor center at Mile 66 of the park road, facing Mount McKinley on clear days, honors pioneer Alaskan aviator Carl Ben Eielson, who died in a 1929 plane crash. Nearby Copper Mountain was renamed Mount Eielson for him in 1930.
Did you know?
In 1924, a decade before a tent camp here took his name, Eielson became the first pilot to land in the park.

Hudson Stuck
As Episcopal Archdeacon of the Yukon, Stuck crossed his vast district by dog sled and boat. He organized the 1913 expedition that made the first ascent of the mountain’s 20,310-foot (6,190 m) south summit on June 7.
Did you know?
Stuck’s account of the climb, published in February 1914, opens with “a plea for the restoration” of the mountain’s “immemorial native name.” He put that name first in the book’s title, The Ascent of Denali (Mount McKinley).

Kahiltna
At about 44 miles (71 km), the Kahiltna is the longest glacier in the park and in the Alaska Range. It flows from the mountain’s southwest side; climbers fly in to base camp on its Southeast Fork, at 7,200 feet (2,195 m).
Did you know?
Earlier ascents had all gone up the Muldrow Glacier, on the mountain’s northeast side. In 1951 pilot Terris Moore flew Bradford Washburn and three others onto the upper Kahiltna, at 7,650 feet (2,332 m). Four more came overland, and all eight reached the summit.

Kantishna
This old gold-mining community lies at the far west end of the 92-mile (148 km) park road. News of strikes on Eureka and Glacier creeks in June 1905 drew thousands of prospectors, and the district joined the park in 1980.
Did you know?
Fannie Quigley, a Nebraska homesteader’s daughter, came with the 1905 stampede and stayed nearly 40 years, mining, hunting and gardening. She kept vegetables and meat cold in nearby prospect tunnels.

Mount McKinley
North America’s tallest peak, 20,310 feet (6,190 m), was named in print in 1897 by a prospector who admired President-elect William McKinley. The Park Service reports its official name became Denali in 2015, then Mount McKinley again by a 2025 executive order.
Did you know?
By the Park Service’s figures, the mountain’s base sits only about 2,000 feet (610 m) above sea level, so it rises about three and a half miles (5.6 km), farther than Mount Everest rises from its 14,000-foot (4,267 m) plain.

Polychrome
This overlook at Mile 45.8 of the park road sits high on Polychrome Mountain, whose descriptive name, meaning “many colors,” suits its vivid volcanic rock. Far below, braided river channels cross the Plains of Murie, with peaks of the Alaska Range beyond.
Did you know?
Just east of the overlook, the Pretty Rocks landslide closed the park road in August 2021. A ribbon-cutting on September 2, 2026, marked the completion of a 475-foot (145 m) steel bridge across it; the Park Service expects full bus service in 2027.

Sable Pass
Wildlife watchers prize this mostly treeless pass, about Miles 37 to 42 of the park road, for caribou, Dall sheep and grizzlies. To leave them undisturbed, a closure dating from 1956 keeps visitors on the road May through September as of 2026.
Did you know?
When the road reached the pass in the late 1920s, tourists could arrive only by train. The closure came as the new Denali Highway raised the prospect of visitors driving their own cars to the park.

Savage River
As of 2026, the paved road open to private cars in summer ends at the Savage River, Mile 15; beyond it, travel is by bus, bike or foot. Its Lower Tanana name, the Park Service says, is Tr'at'egheth No', “From Cottonwood Creek.”
Did you know?
In autumn 1924, cars could jolt over only the first nine miles (14 km) of the new road; horses or wagons carried visitors the rest of the way here. Just 50 of that year’s 200 depot visitors went into the park.

Sled Dogs
The park’s sled dogs began as a patrol force: Harry Karstens, hired in 1921 as the first ranger, founded the kennel to fight poaching. The first dogs were bought on February 23, 1922, and winter patrols lasted months at a time.
Did you know?
The 2026 litter, born March 30, was named for other national parks to mark America’s 250th birthday: Sequoia, Mammoth, Rainier, Teton and Mesa, with a sixth pup, Acadia, joining from a partner kennel.

Talkeetna
Air taxis from this town fly climbers to base camp on the mountain’s south side, but only after they check in and attend an orientation at the park’s ranger station here, renamed the Walter Harper Talkeetna Ranger Station by a 2013 law.
Did you know?
At the ranger station, climbers are issued Clean Mountain Cans, portable toilets first tried in 2001 and required since 2006. As of 2022, all human waste from below 14,200 feet (4,328 m) on the most popular route had to come back to Talkeetna.

Walter Harper
Son of a Koyukon Athabascan mother and an Irish immigrant father, Harper took the lead on summit day and, on June 7, 1913, became the first person to stand on the summit. He died in 1918, when the steamer Princess Sophia sank.
Did you know?
On July 19, 2022, the Walter Harper Project unveiled a bronze statue of him in downtown Fairbanks that includes his dog, Snowball.

Wonder Lake
Near the west end of the park road, this lake, 2.6 miles (4.2 km) long and 280 feet (85 m) deep, was carved out by the Muldrow Glacier. On clear days it offers views of Mount McKinley and the Alaska Range.
Did you know?
Ansel Adams’s photograph of Mount McKinley and Wonder Lake was long dated 1947 or 1948. Astronomer Donald Olson later worked out the exact moment: 3:42 a.m. on July 15, 1948.
