[9] At temperate latitudes wet snow avalanches are frequently associated with climatic avalanche cycles at the end of the winter season, when there is significant daytime warming.
Mountain rescue refers to search and rescue activities that occur in a mountainous environment, although the term is sometimes also used to apply to search and rescue in other wilderness environments.

Crevasse rescue (or crevasse-extraction) is a set of techniques in mountaineering where climbers use their equipment to pull a climber, who has just fallen into a crevasse, to safety. [1] Crevasse rescue is considered a core skill set in alpine climbing , but difficult to do efficiently.
Also called a cable car.

Also datum level or datum line. The zero-elevation baseline or vertical datum to which a measurement of elevation or altitude is relative, e.g. the mean sea level calculated for a given location over a given period of time. [4] See also geodetic datum. de facto segregation The spatial and social separation of populations that occurs without ...
