Map - Salt Lake City (Salt Lake City)

Salt Lake City (SLC), often shortened to Salt Lake, is the capital and most populous city of Utah, United States. It is the seat of Salt Lake County, the most populous county in Utah. With a population of 200,133 in 2020, the city is the core of the Salt Lake City metropolitan area, which had a population of 1,257,936 at the 2020 census. Salt Lake City is further situated within a larger metropolis known as the Salt Lake City–Ogden–Provo Combined Statistical Area, a corridor of contiguous urban and suburban development stretched along a 120 mi segment of the Wasatch Front, comprising a population of 2,746,164 (as of 2021 estimates), making it the 22nd largest in the nation. It is also the central core of the larger of only two major urban areas located within the Great Basin (the other being Reno, Nevada).

Salt Lake City was founded July 24, 1847, by early pioneer 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 planning and building an extensive irrigation network which 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 (the area containing the Salt Lake Temple in downtown Salt Lake City) 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. In 1868, the word "Great" was dropped from the city's name.

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 initially 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.

Salt Lake City has developed a strong tourist industry based primarily on skiing, outdoor recreation, and religious tourism. It hosted the 2002 Winter Olympics and is a candidate city for the 2030 Winter Olympics. It is known for its politically liberal culture, which stands in contrast with the rest of the state's highly conservative leanings. It is home to a significant LGBT community and hosts the annual Utah Pride Festival. It is the industrial banking center of the United States. Salt Lake City and the surrounding area are also the location of several institutions of higher education including the state's flagship research school, the University of Utah. Sustained drought in Utah has more recently strained Salt Lake City's water security and caused the Great Salt Lake level drop to record low levels, and has impacted the local and state economy.

Before settlement by members of the LDS Church, the Shoshone, Weber Ute, and Paiute had dwelt in the Salt Lake Valley for thousands of years. At the time of Salt Lake City's founding, the valley was within the territory of the Northwestern Shoshone. One local Shoshone tribe, the Western Goshute tribe, had names for the Jordan River, City Creek, and Red Butte Canyon (Pi'o-gwût, So'ho-gwût, and Mo'ni-wai-ni). The Goshutes (or, Gosiutes) also lived in the vicinity of Salt Lake and the valleys to the west. The land was treated by the United States as public domain; no aboriginal title by the Northwestern Shoshone was ever ceded or relinquished by treaty with the United States. The first explorer of European descent in the Salt Lake area was likely Jim Bridger in 1825, although others had been in Utah earlier, including some who traveled as far north as the nearby Utah Valley (the 1776 Dominguez-Escalante expedition were undoubtedly aware of Salt Lake Valley's existence). U.S. Army officer John C. Frémont surveyed the Great Salt Lake and the Salt Lake Valley in 1843 and 1845. The Donner Party, a group of ill-fated pioneers, had traveled through the Great Salt Lake Valley in August 1846. The settling of Salt Lake City dates to the arrival of the Latter-day Saints in July 1847. They had traveled beyond the boundaries of the United States into Mexican Territory seeking a secluded area to safely practice their religion away from the violence and the persecution they experienced in the United States. Upon arrival at the Salt Lake Valley, president of the church Brigham Young is recorded as stating, "This is the right place, drive on." Brigham Young is said to have seen the area in a vision before the wagon train's arrival. They found the broad valley empty of any human settlement. The city was not platted till after the federal surveyor abandoned his post in 1857. In 1855 Congress directed the President of the United States to appoint a surveyor general for Utah Territory, and to cause that the lands of that territory should be surveyed preparatory to bringing them on the market. Because of numerous conflicts between the surveyor and the territorial government the first surveyor general abandoned his post in 1857, not to return till 1869.

There was a Native American population in the valley, but an outbreak of measles during the winter of 1847 killed many. The Shoshone saved the pioneers when they taught them to eat the bulb of the native sego lily, which has long been part of the ordinary diet of the Shoshone, sego being derived from the Shoshone word seego. The sego lily was commemorated by the Sego Lily Dam, a flood-prevention infrastructure project in the shape of a giant sego lily, built in Sugar House Park in 2017.

Four days after arriving in the Salt Lake Valley, Brigham Young designated the building site for the Salt Lake Temple. The Salt Lake Temple, constructed on the block later called Temple Square, took 40 years to complete. Construction started in 1853, and the temple was dedicated on April 6, 1893. The temple has become an icon for the city and serves as its centerpiece. The southeast corner of Temple Square is the point of reference for the Salt Lake meridian, and for all addresses in the Salt Lake Valley.

The pioneers organized a state called State of Deseret, and petitioned for its recognition in 1849. The United States Congress rebuffed the settlers in 1850 and established the Utah Territory, vastly reducing its size, and designated Fillmore as its capital city. Great Salt Lake City replaced Fillmore as the territorial capital in 1856, and the name later was shortened to Salt Lake City. The city's population continued to swell with an influx of converts to the LDS Church and Gold Rush gold seekers, making it one of the most populous cities in the American Old West.

The first group of settlers brought African slaves with them, making Utah the only place in the western United States to have African slavery. Three slaves, Green Flake, Hark Lay, and Oscar Crosby, came west with the first group of settlers in 1847. The settlers also began to purchase Indian slaves in the well-established Indian slave trade, as well as enslaving Indian prisoners of war. In 1850, 26 slaves were counted in Salt Lake County. In 1852, the territorial legislature passed the Act in Relation to Service and the Act for the relief of Indian Slaves and Prisoners formally legalizing slavery in the territory. Slavery was abolished in the territory during the Civil War.

Explorer, ethnologist, and author Richard Francis Burton traveled by coach in the summer of 1860 to document life in Great Salt Lake City. He was granted unprecedented access during his three-week visit, including audiences with Brigham Young and other contemporaries of Joseph Smith. The records of his visit include sketches of early city buildings, a description of local geography and agriculture, commentary on its politics and social order, essays, speeches, and sermons from Young, Isaac Morley, George Washington Bradley and other leaders, and snippets of everyday life such as newspaper clippings and the menu from a high-society ball.
