Castle Mountains (California)
The Castle Mountains are located in the Eastern Mojave Desert, in northeastern San Bernardino County, California and Clark County, Nevada. The range lies south and east of the New York Mountains, southwest of Searchlight and west of Cal-Nev-Ari, Nevada. The range lies at the northeastern end of the Lanfair Valley, and reaches an elevation of 5,543 feet above sea level at the summit of Hart Peak. The mountains lie in a southwest-northeasterly direction in both states, although most of the range is in California. The Piute Range lies to the southeast. Canadian NewCastle Gold Ltd. currently holds the rights to the Castle Mountain Mine Area, an open pit gold mine in the southern Castle Mountains. The company has the right to excavate nearly 10 million tons of ore through 2025. Due to low gold prices, however, mining has been suspended since 2001.

The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

National Monument (United States)
In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the President of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. In contrast, national parks in the U.S. cannot be created by presidential proclamation; they require legislation by Congress "because of some outstanding scenic feature or natural phenomena", and serve "inspirational, educational, and recreational values." Some national monuments were first created by presidential action and later designated as national parks by congressional approval. The 129 national monuments are managed by several federal agencies: the National Park Service, United States Forest Service, United States Fish and Wildlife Service, the Bureau of Land Management, and the National Oceanic and ...

Mountain Ranges Of Southern California
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 (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...
