Geography & Physical Attributes
Riddle #1: What is the original Athabascan name for Denali and what does it mean?
The indigenous Athabascan people called the mountain Denali, meaning “The Great One” or “The High One” in their language. The official name was changed to Mount McKinley from 1917-2015 before the traditional name Denali was restored.
Riddle #2: True or False: Denali is the tallest mountain peak wholly within one country.
True. At 20,310 feet, Denali (located in Alaska, USA) is the tallest mountain peak that is completely within one country’s territorial boundaries.
Riddle #3: How prominent and tall is Denali relative to the surrounding terrain?
Denali’s height above surrounding terrain is among the largest of any mountain on Earth at around 18,000 ft (5,500 m). This huge rise over the surrounding lowlands contributes to the impression of Denali’s overwhelming prominence compared to nearby peaks.
Riddle #4: What is the Kahiltna Glacier?
The Kahiltna Glacier is Alaska’s longest glacier and extends from Denali’s south side for over 40 miles (64 km). Nearly all climbing expeditions approach Denali from the Kahiltna Glacier base camp.
Geology
Riddle #5: How old is Denali and what tectonic plate action helped form it?
Denali began forming between 6-10 million years ago as the Pacific Plate subducted under the North American plate, causing compression and crustal thickening. This uplift continues today, slowly increasing the mountain’s height.
Riddle #6: What causes the stubborn snowfields and perennial ice covering Denali?
Despite summer temperatures, Denali holds perennial snowfields and ice year-round largely due to the very high altitude causing freezing temperatures. As well, Denali’s steep slopes cause winter snow and ice to resist melting even in summer.
Riddle #7: Approximately how many glaciers extend from Denali’s slopes?
Denali has approximately 30 named glaciers along its slopes and ridgelines which are continually shaped by gravity and the mountain’s steep form. The largest is the Kahiltna Glacier stretching about 44 miles (71 km) from the peak.
Climate & Weather
Riddle #8: In which climate zone is Denali located?
Denali is located in a subarctic climate zone, characterized by long, frigid winters and short, cool summers. This creates an alpine tundra biome on the mountain up to elevations of 4,500 ft (1,400 m).
Riddle #9: What record does Denali hold regarding temperature differences between its summit and base?
The summit of Denali has an avg winter temperature of -30° F (-35° C) while the base is around 0° F (-18° C), making one of the greatest temperature differences on Earth at 105° F (59° C).
Riddle #10: What speed can the high-elevation winds of Denali reach?
Wind speeds of 135 mph (217 km/h) and higher are common for Denali due to intense weather systems crossing Alaska’s interior. These extreme winds contribute to bitter subzero windchill temperatures.
Flora & Fauna
Riddle #11: What types of birds have been spotted 18,000 feet (5,500 meters) up Denali’s slopes?
Some amazing flight-capable birds like ravens, gyrfalcons and golden eagles have been seen flying at 18,000 feet (5,500 meters) up Denali. At this extreme altitude, even birds struggle to get enough lift and oxygen to fly.
Riddle #12: What unique owl is found only in the Denali region’s boreal forests?
The Great Grey Owl is mostly found in Alaska and western Canada, with dense boreal forests surrounding Denali providing perfect habitat for these elusive giant owls to thrive.
Riddle #13: Approximately how many different species of moss and lichen have been identified on Denali?
Over 400 species mosses and lichens have adapted to survive on Denali’s hostile slopes. They cling to rocky outcrops, grow incredibly slowly, and form crucial groundcover to secure steep alpine soils in place.
History & Culture
Riddle #14: About how long ago did Athabascan indigenous groups first inhabit the Denali region?
Archaeological evidence indicates Athabascan people inhabited the greater Denali region as far back as 8000 BCE leading to Denali and the surrounding lands being sacred to their identity. Indigenous groups still live around and subsistence hunt in Denali today.
Riddle #15: What group of gold prospectors named Denali after a politician in 1917?
Prospector William Dickey named it Mount McKinley after President William McKinley in 1917 against the wishes of Alaska Natives. This name held until 2015 when Barack Obama restored the traditional name Denali meaning “the great one” in Athabascan languages.
Riddle #16: About how many climbers attempt to summit the mountain each year?
Around 1200 climbers make attempts on Denali’s summit each year during the few months when conditions are less extreme, but only around half are successful due to challenging weather, frozen routes, steep slopes and more.
National Park & Tourism
Riddle #17: True or False: Denali National Park is crossed by a major road.
False. Unlike most national parks, Denali has just one narrow gravel road running 92 miles into the park called the Denali Park Road providing vehicle access while preserving backcountry wilderness. No roads cross through Denali to the other side.
Riddle #18: What Transportation restriction is unique to Denali National Park?
Most visitors can only access Denali National Park via special approved buses because there is an unusual ban on private vehicles driving beyond the first 15 miles (24 km) on the Denali Park Road to reduce impact on wildlife and ecosystems.
Riddle #19: In which US state is Denali National Park located?
Alaska is the home of Denali National Park surrounding and including Denali mountain itself. It was founded in 1917 and expanded many times to protect Denali and its ecosystems as a national treasure.
First Ascents & Mountaineering
Riddle #20: Who made the first verifiable summit of Denali and when?
After several failed summit attempts, Hudson Stuck, Harry Karstens, Walter Harper and Robert Tatum made the first undisputed ascent to Denali’s true highest point on June 7, 1913 after decades of attempts.
Riddle #21: True or False: There have been verified winter ascents of Denali’s summit.
True! Although conditions on Denali in winter are among the most severe and life-threatening anywhere, experienced climbers have managed to summit Denali in winter starting when Naomi Uemura made the long, solo climb to the top in February 1984.
Riddle #22: Who was the first female to reach Denali’s summit?
Barbara Washburn became the first woman to summit Denali when she accompanied her husband Bradford Washburn to the top on June 10, 1947 after difficult trailbreaking through snow, ice and wind.
Unique Facts
