Alpine club in the context of "Climbing"

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.

Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports.

Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grading and guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and the location/zone of mountaineering activity (hiking, trekking, or climbing zone). Mountaineering impacts communities on economic, political, social, and cultural levels, often leading to changes in people's worldviews influenced by globalization, specifically foreign cultures and lifestyles.
