Mount Moffit
Rising to 13,020 feet in Alaska’s remote Hayes Range, Mount Moffit is an imposing glaciated summit defined by steep ridges, enormous vertical relief, and a mountaineering history stretching from the pioneering expeditions of the 1940s to major new routes climbed in the 21st century.
Mount Moffit stands in the eastern portion of the Alaska Range, approximately 10 miles east-southeast of Mount Hayes. Although substantially lower than Denali and many of Alaska’s best-known giants, Moffit’s combination of steep terrain, glaciers, difficult access, and technical climbing makes it one of the more formidable mountains in this part of the state.
Its north side is especially dramatic. The mountain rises thousands of feet above the surrounding glaciers in a remarkably short horizontal distance, creating the kind of huge alpine walls for which Alaska is famous.

🗺️ Geography and Setting
Mount Moffit lies within the Hayes Range, a rugged subdivision of the eastern Alaska Range. The Hayes Range contains some of the most prominent mountains east of Denali, including Mount Hayes, Mount Shand, Moby Dick, Mount Deborah, and McGinnis Peak.
Moffit rises near the head of the Trident Glacier, which occupies the deeply carved glacial terrain surrounding several of the region’s major peaks. Its location is extraordinarily remote. There are no hiking trails winding toward the summit and no convenient roadside trailhead from which climbers can begin an ascent.
Instead, expeditions generally depend on aircraft access followed by glacier travel and lengthy approaches through serious alpine terrain.
This isolation is one of the defining characteristics of the Hayes Range. Even compared with other Alaskan mountains, Mount Moffit feels removed from settled landscapes and conventional recreation areas.
The mountain’s approximately 10-mile topographic isolation also gives it a distinct presence despite being surrounded by other major summits.
🏔️ Geology and Glacial Landscape
Mount Moffit belongs to a geologically complex portion of the eastern Alaska Range shaped by tectonic activity, faulting, uplift, erosion, and repeated glaciation.
The eastern Alaska Range contains a complicated assortment of metamorphic, sedimentary, and igneous rocks assembled and transformed through a long history of terrane accretion and crustal deformation. The active Denali fault system also plays an important role in the broader structure of the range.
On Mount Moffit itself, dark gneiss forms part of the mountain’s resistant core. Climbers on the northeast ridge have described transitions between shattered slate-like rock and more compact gneiss, producing a mixture of unstable slopes, steep towers, ridges, and imposing rock faces.
Glaciers have further sculpted the terrain.
Repeated periods of glaciation excavated valleys and steepened mountain faces throughout the Alaska Range. Around Moffit, enormous masses of moving ice have helped create the sharp ridgelines, steep walls, hanging glaciers, crevasses, and moraines encountered by modern climbers.
Mount Moffit’s north face is particularly impressive, dropping roughly 7,400 feet over only about 1.2 horizontal miles. That tremendous relief contributes to the mountain’s reputation as a serious alpine objective.
📜 How Mount Moffit Got Its Name
Mount Moffit commemorates Fred Howard Moffit, one of the most prolific geologists associated with the early U.S. Geological Survey work in Alaska.
Moffit was born in 1874 and spent approximately four decades working with the Alaska Branch of the U.S. Geological Survey. Beginning in 1903, he participated in extensive geological investigations across Alaska, studying regions ranging from the Seward Peninsula to south-central Alaska and the Wrangell Mountains.
He ultimately produced dozens of publications dealing with Alaska’s geology and mineral resources.
The U.S. Geological Survey applied his name to Mount Moffit in 1950. The official geographic record describes the mountain as a 13,020-foot peak near the head of the Trident Glacier.
There is also an unusual naming connection with neighboring Mount Shand.
William Shand Jr., one of Mount Moffit’s first ascensionists, died several years after his historic climbs in the Hayes Range. Bradford Washburn proposed honoring him by naming a mountain for him. The name was eventually attached to the neighboring 12,660-foot summit now known as Mount Shand rather than Mount Moffit.
The result is that two neighboring Hayes Range peaks commemorate very different figures in Alaska history: a pioneering geologist and a pioneering mountaineer.
🧗 Climbing History
Mount Moffit has a surprisingly rich climbing history for such a remote mountain.
First Ascent
The first recorded ascent took place on August 12, 1942, when William Shand Jr., Benjamin Ferris Jr., and Sterling Hendricks reached the summit.
All three climbers were already familiar with this part of the Alaska Range. They had participated in pioneering climbing efforts on nearby Mount Hayes, and their ascent of Moffit came during a period when much of Alaska’s high-mountain terrain remained poorly explored.
The Northwest Ridge became closely associated with the mountain’s early climbing history and remains one of its best-known lines.
Northwest Ridge
A later Northwest Ridge expedition was documented in the American Alpine Journal in 1975, illustrating both the scale of the mountain and the difficulties involved in climbing it.
The route requires extensive glacier travel followed by thousands of feet of climbing over steep snow, ice, rock, and corniced ridges.
Even decades later, the Northwest Ridge remained sufficiently difficult that climbers continued to make repeated attempts before reaching the summit. A 1997 American Alpine Journal account describes climbers negotiating knife-edged ice, exposed ridges, unstable weather, and extended time high on the mountain before finally reaching the top.
Mount Moffit is therefore very different from a peak where a technically straightforward “standard route” provides reliable summit access. Every ascent remains a major Alaska Range expedition.
🧗♂️ The Entropy Wall
One of Mount Moffit’s most important modern climbing achievements came in July 2006, when Jed Brown and Colin Haley climbed a major new route on the north face known as The Entropy Wall.
The wall rises roughly 1,400 meters and combines rock, aid, mixed, and ice climbing.
The route was graded approximately VI 5.9 A2 W4+ and required dozens of pitches followed by extensive snow and ice climbing above the main rock wall.
Its scale demonstrates why Mount Moffit has earned a reputation far beyond what its elevation alone might suggest. The mountain offers huge vertical faces comparable in seriousness to far more famous alpine objectives.
🧊 The 2025 Enthalpy Ridge Ascent
Mount Moffit entered the climbing news again in April 2025, when Dane Steadman and Cody Winckler completed the first ascent of the mountain’s previously unclimbed northeast ridge.
They named the route Enthalpy Ridge.
The climb gained approximately 2,600 meters and was graded M5+ WI3. Steadman and Winckler spent three days climbing the ridge before reaching Mount Moffit’s summit.
The route included steep snow, mixed terrain, shattered rock, compact gneiss towers, a hanging glacier, crevasses, and long sections of exposed alpine climbing.
Rather than reversing the route, the pair descended the Northwest Ridge, completing a traverse of Mount Moffit.
The ascent was included among the significant first ascents of 2025 and demonstrates that, more than 80 years after its first ascent, Mount Moffit still contains major unclimbed alpine terrain.
🌿 Flora and Fauna
Mount Moffit’s summit and upper faces are dominated by snow, glaciers, exposed rock, and severe alpine conditions, so vegetation becomes increasingly sparse with elevation.
Lower terrain in this part of interior Alaska transitions through alpine tundra and eventually into boreal ecosystems.
Alpine tundra vegetation can include low shrubs, sedges, grasses, lichens, mosses, and hardy flowering plants capable of surviving short growing seasons, strong winds, and freezing temperatures. At lower elevations, willow, dwarf birch, white spruce, black spruce, and other plants characteristic of interior Alaska become more common.
Wildlife is more likely to be encountered along the mountain’s lower approaches and surrounding valleys than near the summit itself.
The broader Alaska Range provides habitat for animals such as:
- Dall sheep
- Caribou
- Moose
- Grizzly bears
- Black bears
- Wolves
- Wolverines
- Arctic ground squirrels
- Ptarmigan
- Golden eagles and other raptors
Some of these animals can venture surprisingly high into mountain terrain.
The 2025 Enthalpy Ridge expedition provided a striking example. The climbers reported following wolverine tracks roughly 1,000 meters up the mountain, while bear and wolf tracks were also encountered near their approach to the lower Trident Glacier. A ptarmigan was observed after the climbers returned to the moraine following their descent.
Those encounters underline how even a landscape that appears dominated by rock and ice remains connected to the larger Alaska Range ecosystem.
🌦️ Climate and Weather
Mount Moffit experiences an extremely cold alpine version of the subarctic climate found across this part of Alaska.
Winters are long, cold, and snowy, while summers are short and relatively cool. At high elevations, winterlike conditions can occur at virtually any time of year.
Strong winds are another major concern.
Storms can arrive rapidly, reducing visibility and turning exposed ridges into extremely dangerous terrain. High winds also redistribute snow and help create cornices along ridgelines.
Glacier travel introduces additional hazards including crevasses, unstable snow bridges, serac fall, avalanches, and changing surface conditions.
The enormous elevation difference between surrounding valleys and the summit also means climbers may encounter dramatically different conditions during a single expedition.
🥾 Can You Hike Mount Moffit?
Mount Moffit should not be considered a conventional hiking mountain.
There is no established recreational trail to the summit. Reaching it requires expedition-level mountaineering involving glacier travel, technical climbing, route finding, wilderness camping, and the ability to operate independently in extremely remote terrain.
Aircraft logistics are commonly required simply to reach the surrounding glacier system.
Experienced climbers must also contend with crevasses, avalanches, cornices, falling ice, unstable rock, rapidly changing weather, and very limited rescue options.
For most travelers, Mount Moffit is best appreciated from a distance rather than attempted as a summit objective.
🧭 Why Mount Moffit Matters
Mount Moffit combines nearly every characteristic that makes the Alaska Range exceptional.
It has substantial elevation but is not defined by height alone. Its significance comes from its immense vertical relief, glaciated surroundings, geological complexity, isolation, wildlife, and long history of adventurous climbing.
The mountain also connects several chapters of Alaska history.
Its name preserves the legacy of geologist Fred Howard Moffit. Its first ascent belongs to the early era of Alaska Range exploration. The Entropy Wall represents modern technical alpinism, while the first ascent of Enthalpy Ridge in 2025 shows that meaningful exploration continues even today.
More than eight decades after climbers first stood on its summit, Mount Moffit remains what it has always been: a remote, serious, and remarkably wild mountain.
