Mountaineering in the context of "Ben Nevis"

A secondary city is an urban hub that fills specific regional and local needs related to governance, economics, finance, education, trade, transportation. A secondary city is defined by population, area, function, and economic status, but also by their relationship to neighboring and distant cities and their socio-economic status. A secondary city may emerge from a cluster of smaller cities in a metropolitan region or may be the capital city of a province, state, or second-tier administrative unit within a country. Secondary cities are the fastest-growing urban areas in lower- and middle-income countries, experiencing unplanned growth and development. By 2030, there will be twice as many medium-size cities as there were in 1990, outnumbering the total number of megacities. According to the World Bank, secondary cities make up almost 40% of the world cities population. Many secondary cities in the Global South are expected to undergo massive expansions in the next few decades comparable to city growth in Europe and North America over the past two centuries. These cities are unique environments that generally have limited data and information on infrastructure, land tenure, and planning.

A mountain hut is a building located at high elevation, in mountainous terrain, generally accessible only by foot, intended to provide food and shelter to mountaineers, climbers and hikers. Mountain huts are usually operated by an alpine club or some organization dedicated to hiking or mountain recreation. They are known by many names, including alpine hut, mountain shelter, mountain refuge, mountain lodge, and mountain hostel. It may also be called a refuge hut, although these occur in lowland areas (e.g. lowland forests) too.

Mountain huts can provide a range of services, starting with shelter and simple sleeping berths. Some, particularly in remote areas, are not staffed, but others have staff which prepare meals and drinks and can provide other services, including providing lectures and selling clothing and small items. Permanent staffing is not possible above the highest permanent human settlements, which are 5500m at the latitude of Everest (27°59′, similar to Corpus Christi, Texas) but lower than 3500m at the latitude of Mont Blanc (45°50', similar to Montreal, Quebec). Permanent staffing has been tried long ago e.g. at Vallot Hut (4362 m, .58 atm) in 1890-91 but had to stop after heart or lung problems apparently due to altitude and cold combined. Mountain huts usually allow anybody to access their facilities, although some require reservations.

Ski mountaineering (abbreviated to skimo) is a skiing discipline that involves climbing mountains either on skis or carrying them, depending on the steepness of the ascent, and then descending on skis. There are two major categories of equipment used: free-heel Telemark skis and skis based on Alpine skis, where the heel is free for ascents, but is fixed during descent. The discipline may be practiced recreationally or as a competitive sport.

Competitive ski mountaineering is typically a timed racing event that follows an established trail through challenging winter alpine terrain while passing through a series of checkpoints. Racers climb and descend under their own power using backcountry skiing equipment and techniques. More generally, ski mountaineering is an activity that variously combines ski touring, Telemark, backcountry skiing, and mountaineering.

A massif (/mæˈsiːf, ˈmæsɪf/) is a principal mountain mass, such as a compact portion of a mountain range, containing one or more summits (e.g. France's Massif Central). In mountaineering literature, massif is frequently used to denote the main mass of an individual mountain.

As a purely scientific term in geology, however, a "massif" is separately and more specifically defined as a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology.

In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants.

Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted mountaineering gear, has made canopy observation significantly easier and more accurate, allowed for longer and more collaborative work, and broaddened the scope of canopy study.

Gilgit (/ˈɡɪlɡɪt/; Shina: گِلیٗت IPA: [ɡi˧.leː˨˦t̪]; Urdu: گِلْگِت IPA: [ˈɡɪlɡɪt̪]) is the capital and most-populous city in Pakistani-administered Gilgit–Baltistan in the disputed Kashmir region. It is located in a broad valley near the confluence of the Gilgit and the Hunza rivers. It is a major tourist destination in Pakistan, serving as a hub for trekking and mountaineering expeditions in the Karakoram mountain range of Northern Pakistan.

Gilgit was once a major centre for Buddhism; it was an important stop on the ancient Silk Road, and today serves as a major junction along the Karakoram Highway with road connections to China as well as the Pakistani cities of Skardu, Chitral, Peshawar, and Islamabad. The city's economic activity is mainly focused on agriculture, with wheat, maize, and barley as the main crops.

Chimborazo (Spanish: [tʃimboˈɾaso] ) is a stratovolcano in Ecuador and the Cordillera Occidental range of the Andes. Its last known eruption is believed to have occurred around AD 550. Although not the tallest mountain in the Andes or on Earth relative to sea level, its summit is the farthest point on Earth's surface from the Earth's center due to its location along the planet's equatorial bulge. Chimborazo's height from sea level is 6,263 m (20,548 ft), well below that of Mount Everest at 8,849 m (29,031 ft).

Chimborazo is the highest mountain in Ecuador and the 39th-highest peak in the entire Andes. It is a popular destination for mountaineering due to its challenging climbing routes, which involve traversing snow, ice, and rocky terrain.
