Great Salt Lake in the context of "Salt Lake County, Utah"

Following are two lists of terrestrial lakes that have surface areas of more than approximately 3,000 square kilometres (1,200 sq mi), ranked by area, excluding reservoirs and lagoons.

The area of some lakes can vary over time, either seasonally or from year to year. This is especially true of salt lakes in arid climates.This list therefore excludes seasonal lakes such as Kati Thanda–Lake Eyre (maximum area 9,500 km, 3,700 sq mi), Mar Chiquita Lake (Córdoba) (maximum area 6,000 km, 2,300 sq mi), Chott el Djerid (up to 7,000 km, 2,700 sq mi, Lake Torrens (maximum area 5,745 km, 2,218 sq mi) and Great Salt Lake (maximum area, 1988, 8,500 km, 3,300 sq mi).

Halobacterium (common abbreviation Hbt.), from Ancient Greek ἅλς (háls), meaning "salt", and "bacterium", is a genus in the family Halobacteriaceae.

The genus Halobacterium ("salt" or "ocean bacterium") consists of several species of Archaea with an aerobic metabolism which requires an environment with a high concentration of salt; many of their proteins will not function in low-salt environments. They grow on amino acids in their aerobic conditions. Their cell walls are also quite different from those of bacteria, as ordinary lipoprotein membranes fail in high salt concentrations. In shape, they may be either rods or cocci, and in color, either red or purple. They reproduce via binary fission (constriction), and are motile. Halobacterium grows best in a 42 °C environment. The genome of an unspecified Halobacterium species, sequenced by Shiladitya DasSarma, comprises 2,571,010 bp (base pairs) of DNA compiled into three circular strands: one large chromosome with 2,014,239 bp, and two smaller ones with 191,346 and 365,425 bp. This species, called Halobacterium sp. NRC-1, has been extensively used for postgenomic analysis. Halobacterium species can be found in the Great Salt Lake, the Dead Sea, Lake Magadi, and any other waters with high salt concentration. Purple Halobacterium species owe their color to bacteriorhodopsin, a light-sensitive membrane protein which acts as a proton pump, providing chemical energy with the proton gradient for the cell using light energy. The resulting proton gradient across the cell membrane is used to drive ATP synthase to generate adenosine triphosphate (ATP). Bacteriorhodopsin is very similar to rhodopsin, light-sensitive receptor proteins found in the retina of most animals.

Salt Lake City, often shortened to Salt Lake or SLC, is the capital and most populous city of the U.S. state of Utah. It is the county seat of Salt Lake County, the most populous county in the state. The population was 199,723 at the 2020 census, while the Salt Lake City metropolitan area has an estimated 1.3 million residents and is the 46th-largest metropolitan area in the United States. It is also part of the larger Salt Lake City–Ogden–Provo combined statistical area, an urban corridor along a 120-mile (190 km) segment of the Wasatch Front with a population of approximately 2.8 million. It is one of the principal urban centers within the Great Basin, along with Reno, Nevada.

Salt Lake City was founded in 1847 by settlers led by Brigham Young who were seeking to escape persecution they had experienced while living farther east. The Mormon pioneers, as they would come to be known, entered a semi-arid valley and immediately began building an extensive irrigation network that could feed the population and foster future growth. Salt Lake City's street grid system is based on a standard compass grid plan, with the southeast corner of Temple Square serving as the origin of the Salt Lake meridian. Owing to its proximity to the Great Salt Lake, the city was originally named Great Salt Lake City; the word "Great" was dropped from the city's name in 1868. Immigration of international members of the Church of Jesus Christ of Latter-day Saints (LDS Church), mining booms, and the construction of the first transcontinental railroad brought economic growth, and the city was nicknamed "The Crossroads of the West". It was traversed by the Lincoln Highway, the first transcontinental highway, in 1913. Two major cross-country freeways, I-15 and I-80, now intersect in the city. The city also has a belt route, I-215.

A waterspout is a rotating column of air that occurs over a body of water, usually appearing as a funnel-shaped cloud in contact with the water and a cumuliform cloud. There are two types of waterspout, each formed by distinct mechanisms. The most common type is a weak vortex known as a "fair weather" or "non-tornadic" waterspout. The other less common type is simply a classic tornado occurring over water rather than land, known as a "tornadic", "supercellular", or "mesocyclonic" waterspout, and accurately a "tornado over water". A fair weather waterspout has a five-part life cycle: formation of a dark spot on the water surface; spiral pattern on the water surface; formation of a spray ring; development of a visible condensation funnel; and ultimately, decay. Most waterspouts do not suck up water.

While waterspouts form mostly in tropical and subtropical areas, they are also reported in Europe, Western Asia (the Middle East), Australia, New Zealand, the Great Lakes, Antarctica, and on rare occasions, the Great Salt Lake. Some are also found on the East Coast of the United States, and the coast of California. Although rare, waterspouts have been observed in connection with lake-effect snow precipitation bands.

Ogden (/ˈɒɡ.dən/ OG-dən) is a city in and the county seat of Weber County, Utah, United States, located approximately 10 miles (16 km) east of the Great Salt Lake and 40 miles (64 km) north of Salt Lake City. The population was 87,321 in 2020, according to the United States Census Bureau, making it Utah's eighth largest city. The city served as a major railway hub through much of its history, and still handles a great deal of freight rail traffic which makes it a convenient location for manufacturing and commerce. Ogden is also known for its many historic buildings, proximity to the Wasatch Mountains, and as the location of Weber State University.

Ogden is a principal city of the Ogden-Clearfield metropolitan area, which includes all of Weber, Morgan, Davis, and Box Elder counties. The 2010 Census placed the Metro population at 597,159. In 2010, Forbes rated the Metro as America's 6th best place to raise a family. Ogden has had a sister city relationship to Hof in Bavaria, Germany, since 1954.

Promontory is an area of high ground in Box Elder County, Utah, United States, 32 mi (51 km) west of Brigham City and 66 mi (106 km) northwest of Salt Lake City. Rising to an elevation of 4,902 feet (1,494 m) above sea level, it lies to the north of the Promontory Mountains and the Great Salt Lake. It is notable as the location of Promontory Summit, where the first transcontinental railroad in the United States, from Sacramento to Omaha, was officially completed on May 10, 1869. The location is sometimes confused with Promontory Point, a location further south along the southern tip of the Promontory Mountains. Both locations are significant to the Overland Route: Promontory Summit was where the original, now abandoned, alignment crossed just north of the Promontory Mountains; while Promontory Point is where the modern alignment, called the Lucin Cutoff, crosses the southern tip of the Promontory Mountains.

By the summer of 1868, the Central Pacific (CP) had completed the first rail route through the Sierra Nevada mountains, and was now moving down towards the Interior Plains and the Union Pacific (UP) line. More than 4,000 workers, of whom two thirds were Chinese, had laid more than 100 mi (160 km) of track at altitudes above 7,000 ft (2,100 m). In May 1869, the railheads of the Union Pacific and the Central Pacific railroads finally met at Promontory Summit, Utah Territory. A specially-chosen Chinese and Irish crew had taken only 12 hours to lay the final 10 mi (16 km) of track in time for the ceremony.
