The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that includes Arizona and New Mexico, along with adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Before 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854.
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time (UTC−07:00) is in effect, and by subtracting six hours during daylight saving time (UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71.
The Lost Dutchman's Gold Mine is, according to legend, a rich gold mine hidden in the southwestern United States. The location is generally believed to be in the Superstition Mountains, near Apache Junction, east of Phoenix, Arizona. There have been many stories about how to find the mine, and each year people search for the mine. Some have died on the search.
A silver rush is the silver-mining equivalent of a gold rush, where the discovery of silver-bearing ore sparks a mass migration of individuals seeking wealth in the new mining region.

In the United States, gold mining has taken place continually since the discovery of gold at the Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793, but created no excitement. The discovery on the Reed farm in 1799 which was identified as gold in 1802 and subsequently mined marked the first commercial production.
Planchas de Plata, sometimes called Bolas de Plata is a historic silver-mining district near Nogales, Sonora, Mexico, and a few miles south of the border with the US state of Arizona. Native silver was discovered here in 1736 by Antonio Siraumea, a Yaqui Indian, on the Rancho Arizona of Bernardo de Urrea. Historian Donald Garate believes Urrea's Arizona Ranch to be the likely source of the name of the present US state of Arizona, and he claimed the origin of the name of the ranch was the Basque phrase "aritz ona". Other historians have, however, debated this. For more detail on the etymology of the name Arizona, see Arizona.
Toward the end of last October, between the Guevavi Mission and the ranchería called Arizona, some balls and slabs of silver were discovered, one of which weighed more than one hundred arrobas, a sample of which I am sending to you, Most Illustrious Lord. --Captain Juan Bautista de Anza to Bishop Benito Crespo, January 7, 1737.

Cerro Colorado is a ghost town in southern Pima County, Arizona. The town is located off Arivaca Road, near Arivaca, and is best known for the massacre of mining employees by Mexican outlaws and buried treasure.
Emeralds are green and sometime green with a blueish-tint precious gemstones that are mined in various geological settings. They are minerals in the beryl group of silicates. For more than 4,000 years, emeralds have been among the most valuable of all jewels. Colombia, located in northern South America, is the country that mines and produces the most emeralds for the global market, as well as the most desirable. It is estimated that Colombia accounts for 70–90% of the world's emerald market. While commercial grade emeralds are quite plentiful, fine and extra fine quality emeralds are extremely rare. Colombian emeralds over 50 carat can cost much more than diamonds of the same size.
Elgin Bryce Holt was an American geologist, mine owner and engineer, amateur scientist, anthropologist and entrepreneur who reorganized and managed the Cerro de Plata Mining Company in Magdalena, Sonora, Mexico.
