Mountain Rescue Agencies
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Organizations Based In Los Angeles County, California
An organization or organisation ( Commonwealth English; see spelling differences) is an entity—such as a company, or corporation or an institution (formal organization), or an association—comprising one or more people and having a particular purpose. Organizations may also operate secretly or illegally in the case of secret societies, criminal organizations, and resistance movements. And in some cases may have obstacles from other organizations (e.g.: MLK's organization). What makes an organization recognized by the government is either filling out incorporation or recognition in the form of either societal pressure (e.g.: Advocacy group), causing concerns (e.g.: Resistance movement) or being considered the spokesperson of a group of people subject to negotiation (e.g.: the Polisario Front being recognized as the sole representative of the Sahrawi people and forming a partially recognized state.) Compare the concept of social groups, which may include non-org ...
