Mount Clay
Rising along the exposed crest of New Hampshire’s Presidential Range, Mount Clay is a rugged 5,531-foot summit situated between Mount Jefferson and Mount Washington. Although overshadowed by its taller neighbors, Mount Clay offers some of the finest above-treeline scenery in the White Mountains.
The mountain occupies an especially dramatic position above the Great Gulf, where steep glacially carved slopes drop away from the Presidential ridge. Hikers crossing Mount Clay encounter exposed rock, low alpine vegetation, sweeping views, and weather conditions that can change remarkably quickly.
Mount Clay is also unusual because it has effectively carried two names. New Hampshire renamed the mountain Mount Reagan in 2003, but the federal government retained Mount Clay as its official geographic name. Most hiking maps, guidebooks, and national geographic databases therefore continue to identify the summit as Mount Clay.

🏔️ Geography of Mount Clay
Mount Clay occupies the high ridge immediately north of Mount Washington and south of Mount Jefferson. It forms part of the northern section of the Presidential Range, one of the most spectacular high-mountain landscapes in the northeastern United States.
The summit reaches approximately 5,531 feet, according to modern lidar-based elevation data.
Despite that considerable elevation, Mount Clay has only about 142 feet of topographic prominence. Its high connecting saddles with the surrounding Presidential ridge mean that it does not rise far enough above adjacent terrain to qualify as an independent New Hampshire 4,000-footer under the commonly used 200-foot prominence standard.
Its Peakbagger-listed Nearest Higher Neighbor is the Great Gulf Wilderness High Point, located to the southeast. This is not an independent mountain but a slope point associated with Mount Washington.
Because of its limited prominence, Mount Clay often receives less attention than Mount Washington, Mount Adams, or Mount Jefferson. On the ground, however, it feels every bit like a major alpine summit.
🌄 The Great Gulf
One of Mount Clay’s defining geographical features is its position above the Great Gulf, the enormous glacial cirque cut into the eastern side of the northern Presidentials.
From Mount Clay, the terrain falls dramatically toward the floor of the Great Gulf. Across the basin rise the steep slopes and ridges associated with Mount Washington, Mount Jefferson, Mount Adams, and Mount Madison.
Glacial ice helped sculpt this landscape during the Pleistocene, carving deep valleys and steep headwalls into the Presidential Range. The resulting terrain gives Mount Clay some exceptionally dramatic viewpoints.
Looking eastward from the ridge can feel very different from looking west. To the east lies the deep wilderness of the Great Gulf; to the west, the terrain descends toward the Ammonoosuc River valley and the Mount Washington Cog Railway corridor.
The contrast makes Mount Clay an outstanding vantage point for understanding the geography of the northern White Mountains.
🥾 Hiking Mount Clay
Mount Clay is most commonly reached as part of a longer hike through the northern Presidential Range rather than as an isolated summit objective.
The Mount Clay Loop leaves the Gulfside Trail, crosses the summit area, and then reconnects with the main ridge route.
The Gulfside Trail itself is one of the principal high-elevation trails of the Presidentials and forms part of the Appalachian Trail through this section of the White Mountains.
Mount Clay Loop
For hikers already traveling along the Gulfside Trail, the Mount Clay Loop provides the most direct way to visit the actual summit.
The loop is roughly 1.2 miles long and passes over Mount Clay rather than skirting around its slopes.
Hikers completing a Presidential Traverse may choose to include Mount Clay as an additional summit between Mount Jefferson and Mount Washington.
Because Mount Clay is not one of the officially ranked New Hampshire 4,000-footers, some traverse itineraries bypass the summit. For hikers interested in scenery rather than simply checking peaks from a list, however, the detour is worthwhile.
Jewell Trail Approach
The Jewell Trail provides another common approach to this section of the Presidential Range.
Beginning on the western side of Mount Washington, the trail climbs steadily through forest before breaking above treeline and reaching the Gulfside Trail.
From there, hikers can travel north toward Mount Clay or south toward Mount Washington.
Combining the Jewell Trail, Gulfside Trail, and Mount Clay Loop can create an excellent alpine outing, although the overall trip remains strenuous and highly exposed once above treeline.
Presidential Traverse
Mount Clay also lies directly along the corridor followed by many hikers completing the famous Presidential Traverse.
A northern Presidential itinerary typically links some combination of:
- Mount Madison
- Mount Adams
- Mount Jefferson
- Mount Clay
- Mount Washington
From there, longer traverses continue south toward Mount Monroe, Mount Eisenhower, Mount Pierce, and sometimes additional peaks.
Mount Clay is technically optional on many Presidential Traverse routes because the Gulfside Trail can pass around the summit. Adding the Mount Clay Loop, however, provides another excellent viewpoint and a more complete journey along the ridge.
🌿 Flora and Fauna
Mount Clay lies within one of the most important alpine ecosystems in the eastern United States.
Much of the upper mountain is above treeline, where vegetation must survive persistent wind, cold temperatures, shallow soils, ice, snow, and an extremely short growing season.
Alpine Plants
The Presidential Range contains the largest extensive alpine tundra environment in the eastern United States and supports an unusually rich collection of arctic-alpine plants.
Species found throughout the high Presidentials can include:
- Diapensia
- Alpine azalea
- Lapland rosebay
- Mountain cranberry
- Bilberry
- Black crowberry
- Alpine grasses and sedges
- Mosses and lichens
These plants typically grow close to the ground, where they receive some protection from intense wind.
Many grow extremely slowly.
What might appear to be a small patch of vegetation beside the trail can represent decades of growth, which is why hikers should remain on durable rock surfaces and established trails whenever possible.
Krummholz
Near treeline, hikers encounter krummholz—stunted and twisted spruce and fir shaped by years of wind, ice, snow, and cold.
Black spruce and balsam fir that might become tall forest trees at lower elevations can remain only a few feet high in this environment.
Their distorted appearance provides a visible indication of how severe the climate becomes as hikers approach the exposed Presidential ridge.
Wildlife
The exposed summit itself supports fewer large animals than the surrounding forests, but wildlife is still part of the Mount Clay ecosystem.
Common ravens frequently travel across the high ridges, seemingly using the powerful mountain winds with little effort.
American pipits may also occur in alpine environments during the warmer months.
Lower on the mountain, the spruce-fir forests surrounding the Presidentials can support species such as:
- Moose
- Black bears
- Snowshoe hares
- Red squirrels
- Spruce grouse
- Bicknell’s thrush
The transition from northern hardwood forest to spruce-fir forest, krummholz, and finally alpine tundra creates a remarkable sequence of ecological communities over a relatively short vertical distance.
🌸 Protecting the Alpine Zone
The alpine vegetation surrounding Mount Clay is beautiful but extraordinarily fragile.
Plants growing in the Presidentials have adapted to severe natural conditions, but that does not necessarily make them resistant to trampling.
Walking repeatedly across alpine vegetation can damage plants and compact the thin soil beneath them. Recovery may take years.
Hikers should therefore follow established trails and walk on exposed rock whenever practical rather than cutting across vegetated areas.
Climate change presents an additional challenge.
Research in the Presidential Range has documented upward movement of treeline in some areas. As climatic conditions change, species adapted specifically to the limited alpine environment may find themselves with progressively less suitable habitat.
Protecting these small high-elevation ecosystems has therefore become an important conservation priority.
📜 Why Is It Called Mount Clay?
Mount Clay was named for Henry Clay, one of the most influential American politicians of the early 19th century.
Clay served as a U.S. senator, speaker of the House of Representatives, and secretary of state and became widely known as the “Great Compromiser” for his involvement in major political compromises during the decades preceding the American Civil War.
Unlike most of the major Presidential peaks, Mount Clay was therefore not named for a president.
Other exceptions within the broader range include Mount Webster, named for Daniel Webster, and Mount Jackson, named for geologist Charles Thomas Jackson rather than President Andrew Jackson.
🇺🇸 Mount Clay or Mount Reagan?
Mount Clay has one of the more unusual naming histories in the White Mountains.
In 2003, the New Hampshire legislature passed legislation changing the mountain’s name from Mount Clay to Mount Reagan, honoring former President Ronald Reagan. The legislation was signed by the governor.
The change did not settle the matter nationally.
Geographic names used by federal agencies are overseen by the U.S. Board on Geographic Names. In 2010, the federal board declined to adopt the Mount Reagan name and retained Mount Clay.
As a result, New Hampshire state law recognizes Mount Reagan, while federal geographic usage continues to recognize Mount Clay.
Most modern hiking resources and mountain databases use Mount Clay, which is also the name hikers are most likely to encounter when researching routes through the Presidential Range.
🌦️ Weather and Hiking Safety
Mount Clay may be lower than Mount Washington, but hikers should not interpret its slightly lower elevation as protection from severe Presidential Range weather.
The summit is completely exposed.
Strong winds, dense fog, heavy rain, thunderstorms, cold temperatures, snow, and ice can occur in the high Presidentials. Conditions can deteriorate rapidly, including during months when temperatures are warm in the valleys.
The proximity of Mount Washington is particularly important because the entire high ridge shares its extreme alpine climate.
Hikers should carry appropriate layers even during summer, including insulation and a waterproof and windproof outer shell.
A hat, gloves, navigation tools, water, food, and a headlamp are sensible equipment for a Presidential Range hike.
Forecasts for the higher summits should always be checked before beginning the climb.
Turning around is sometimes the best decision available.
The Presidential Range has a long history of search-and-rescue incidents involving hikers who underestimated changing weather. Mount Clay’s accessibility from established trails does not eliminate those risks.
🍂 Best Time to Hike Mount Clay
For most hikers, summer through early fall provides the most practical opportunity to visit Mount Clay.
Late Spring
Snow and ice can linger surprisingly late in the high Presidentials. Alpine plants begin emerging as conditions moderate, and wildflowers often become a highlight of the early growing season.
Summer
Summer generally provides the largest window for hiking, although cold rain, fog, high winds, and dramatic temperature changes remain possible.
Alpine vegetation makes this an especially beautiful period to visit.
Early Fall
September can produce exceptional visibility and colorful foliage in the valleys below.
Temperatures also decline quickly, however, and winter-like weather can return to the Presidential ridge well before snow reaches lower elevations.
Winter
Winter climbing on Mount Clay should be considered serious mountaineering rather than ordinary hiking.
Snow, extreme wind chills, poor visibility, ice, and rapidly changing conditions make the northern Presidentials demanding even for experienced winter travelers.
🏆 Is Mount Clay a New Hampshire 4,000-Footer?
Mount Clay easily exceeds 4,000 feet in elevation, but it does not appear as an independently ranked peak on the traditional New Hampshire 4,000-footer list.
The reason is prominence.
Mount Clay rises only about 142 feet above its key col, while the commonly used qualifying standard for the New Hampshire 4,000-footers requires approximately 200 feet of topographic prominence.
It is therefore treated as a subsidiary summit rather than an independent 4,000-footer.
That technical distinction does little to diminish the hiking experience.
Standing at more than 5,500 feet above sea level with the Great Gulf dropping away nearby and Mount Washington dominating the southern skyline, Mount Clay feels very much like a mountain of its own.
🏞️ A Quiet Highlight of the Presidential Range
Mount Clay may never command the attention given to Mount Washington, Mount Adams, or Mount Jefferson, but that is part of its appeal.
It occupies one of the finest stretches of alpine terrain in New England while remaining a secondary objective for many hikers.
Those who take the Mount Clay Loop are rewarded with sweeping views across the Great Gulf, close-up perspectives of Mount Washington and Mount Jefferson, rare alpine vegetation, and an opportunity to experience the raw character of the northern Presidentials.
Whether visited during a Presidential Traverse, approached from the Jewell Trail, or combined with another summit, Mount Clay deserves more than a passing glance.
It is a rugged, exposed, ecologically important summit in the heart of one of America’s most remarkable mountain landscapes.
