White Mountains (New Hampshire) in the context of "White Mountain National Forest"

Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level and merges with polar tundra.

The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as krummholz. With increasing elevation it ends at the snow line where snow and ice persist through summer.

The Franconia Range is a mountain range located in the White Mountains of the U.S. state of New Hampshire. It is the second-highest range of peaks (after the Presidential Range) in the White Mountains.

Franconia Ridge is a prominent ridge which forms the backbone of the range, stringing together all of its major summits.

Ecosystem ecology is the integrated study of living (biotic) and non-living (abiotic) components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. Ecosystem ecologists study these relationships on large scales, linking biological diversity with ecosystem sustainability and function.

Ecosystem ecology examines physical and biological structures and examines how these ecosystem characteristics interact with each other. Ultimately, this helps us understand how to maintain high quality water and economically viable commodity production. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions.

The Hudson River School was a mid-19th-century American art movement embodied by a group of landscape painters whose aesthetic vision was influenced by Romanticism. Early on, the paintings typically depicted the Hudson River Valley and the surrounding area, including the Catskill, Adirondack, and White Mountains.

Works by second-generation artists expanded to include other locales in New England, the Maritimes, the Western United States, and South America.

Carroll is a town in Coös County, New Hampshire, United States. The population was 820 at the 2020 census. The two largest villages are Twin Mountain and Bretton Woods. Carroll is an important access point for recreational areas in the White Mountains, including many 4,000-footers, the Zealand River area, the Presidential Range, and the Presidential Dry River Wilderness. The town is home to the Mount Washington Hotel at Bretton Woods and to the Highland Center at Crawford Notch, the Appalachian Mountain Club's four-season lodge.

Carroll is part of the Berlin, NH-VT Micropolitan Statistical Area.

Crawford Notch is a major pass through the White Mountains of New Hampshire, located in Hart's Location. Roughly half of that town is contained in Crawford Notch State Park. The high point of the notch, at approximately 1,900 feet (580 m) above sea level, is at the southern end of the town of Carroll, near the Crawford Depot train station and Saco Lake, the source of the Saco River, which flows southward through the steep-sided notch. North of the high point of the notch, Crawford Brook flows more gently northwest to the Ammonoosuc River, a tributary of the Connecticut River.

The notch is traversed by U.S. Route 302, which closely follows the Saco River southeast to North Conway and less closely follows the Ammonoosuc River northwest to Littleton.

Twin Mountain is an unincorporated community in the town of Carroll, New Hampshire, United States. Located in the White Mountains, it is named for two prominent summits which rise to the south of the village: North Twin Mountain (4,761 ft or 1,451 m) and South Twin Mountain (4,902 ft or 1,494 m).

The village is located at the junction of U.S. highways 3 and 302, two major routes through the White Mountain notches. The Ammonoosuc River flows through the center of the village.

The Presidential Range is a mountain range located in the White Mountains of the U.S. state of New Hampshire. It contains the highest peaks of the Whites, the most notable of which are named for American presidents, followed by prominent public figures of the 18th and 19th centuries. The Presidential Range is notorious for having some of the worst weather on Earth, mainly because of the unpredictability of high wind speeds and whiteout conditions on the higher summits. Because of the poor weather conditions, the Presidential Range is often used for mountaineering training for those who go on to climb some of the world's highest mountains, including K2 and Everest.

Mount Washington, long home of the highest winds recorded on the surface of the Earth at 231 mph (372 km/h), is the tallest at 6,288 ft (1,917 m), followed by neighboring peaks Mount Adams at 5,793 ft (1,766 m) and Mount Jefferson at 5,712 ft (1,741 m). The range is almost entirely in Coos County.
