Manhattan, Nevada
Manhattan is an unincorporated town in Nye County, Nevada, located at the end of Nevada State Route 377, about north of Tonopah, the county seat. History It originally was founded in 1867 as part of the silver mining boom. George Wheeler found the district abandoned in 1871. Then, in 1905, as part of the gold boom, "4,000 people flood(ed) into the region". The Nye and Ormsby County Bank, the only stone structure to be built in the town, was erected in 1906, but a decline followed the 1906 San Francisco earthquake and the 1907 depression. The bank was forced to close. In 1904, "Mom" Ronzone first started selling socks to Manhattan miners, the beginning of a retail career that would result in Ronzone's department stores in Tonopah, then Las Vegas. Another boom in 1909 resulted in mining continuing into the late 1940s. Major mining operations opened and operated through the 1970s to the 1990s, but production has recently scaled back significantly. Regional geology The Big ...

Antler Orogeny
The Antler orogeny was a tectonic event that began in the early Late Devonian with widespread effects continuing into the Mississippian and early Pennsylvanian. Most of the evidence for this event is in Nevada but the limits of its reach are unknown. A great volume of conglomeratic deposits of mainly Mississippian age in Nevada and adjacent areas testifies to the existence of an important tectonic event, and implies nearby areas of uplift and erosion, but the nature and cause of that event are uncertain and in dispute. Although it is known as an orogeny (mountain building event), some of the classic features of orogeny as commonly defined such as metamorphism, and granitic intrusives have not been linked to it. In spite of this, the event is universally designated as an orogeny and that practice is continued here. This article outlines what is known and unknown about the Antler orogeny and describes three current theories regarding its nature and origin. Two facies of lower ...

Orogeny
Orogeny is a mountain building process. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. An ''orogenic belt'' or ''orogen'' develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere ( crust and uppermost mantle). A synorogenic process or event is one that occurs during an orogeny. The word "orogeny" () comes from Ancient Greek (, , + , , ). Although it was used before him, the term was employed by the American geologist G. K. Gilbert in 1890 to describe the process of mountain-building as distinguished f ...

Death Valley
Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert. During summer, it is the Highest temperature recorded on Earth, hottest place on Earth. Death Valley's Badwater Basin is the point of lowest elevation in North America, at below sea level. It is east-southeast of Mount Whitney — the highest point in the contiguous United States, with an elevation of 14,505 feet (4,421 m). On the afternoon of July10, 1913, the National Weather Service, United States Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Furnace Creek, California, Furnace Creek in Death Valley, which stands as the Highest temperature recorded on Earth, highest ambient air temperature ever recorded on the surface of the Earth. This reading, however, and several others taken in that period are disputed by some modern experts. Lying mostly in Inyo County, California, near the border of California and Nevada, in the Great ...

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada.
