History

This area was occupied for thousands of years by cultures of indigenous peoples.


19th century

The future Salt Lake County area was settled by European Americans in 1847 when

after descending what settlers later called Emigration Canyon. Brigham Young, their leader, declared " This is the place" after seeing the valley. Compared to eastern regions, it seemed arid and unpromising to some of the migrants. Settlers used irrigation to develop agriculture and the flourishing, self-sufficient city known then as
Great Salt Lake City Salt Lake City (often shortened to Salt Lake and abbreviated as SLC) 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 c ...
. Thousands of Mormons joined them in the next several decades. Settlers buried thirty-six Native Americans in one grave after an outbreak of measles occurred during the winter of 1847. The initial territorial settlement was in Great Salt Lake City proper, but Brigham Young desired to secure a substantial population base across the then-uninhabited Great Basin, so he soon asked members to resettle farther out from the central point. They declared themselves a state ( State of Deseret) in hopes of gaining admittance to the Union, and to assure the nascent state would grow uniformly, they named an as-yet-unbuilt settlement in mid-state as the state's capital (

). The county was officially organized on January 31, 1850, with slightly more than 11,000 residents recorded. 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. The idea of statehood for the new area was quickly tossed aside by the federal government, and the area was declared a territory in September 1850 – the Utah Territory. Construction of the capitol building in Fillmore was completed in 1855, so the territorial legislature traveled to the small community for their first session there. It was to be their last, as they chose to meet in Great Salt Lake City the following year and, in 1857, formally voted to make Salt Lake City (the shorter name adopted in 1857) the capital of the Territory. In 1858, when the Utah Territory was declared in rebellion, the federal government sent troops to install a new governor and keep watch over the area. The government transition was made peacefully, then the troops set up Camp Floyd to the south in Utah County. In 1862, Fort Douglas was established on the eastern bench, near the current site of the University of Utah, as the federal government wanted to ensure the loyalty of the territory during the American Civil War. Patrick Edward Connor, the leader of the garrison at Fort Douglas, was openly

However, the Bingham Canyon Mine kept on expanding. In the early 21st century, it is among the largest open-pit mines in the world.


20th century

After the railroad came to the county, the population began to expand more rapidly, and non-Mormons began to settle in Salt Lake City. During the early 20th century, the heavy industry came to the valley as well, diversifying its economy. Local and interurban trolley systems were built covering the more urban northeastern quarter of the valley. The city dismantled the trolley system by 1945, favoring the use of individual

s. Throughout the late 19th and early 20th centuries, the east side of the valley began to be more densely settled. In 1942, Kearns Army Air Base, a large military installation developed for World War II, was located in what is now Kearns on the western side of the valley. After the camp was closed in 1946, the land was sold for private development. Rapid postwar residential settlement of the area began. The federal government established other major defensive installations along the

West Valley City was created from the merger of the three unincorporated cities of Granger, Hunter and Redwood (including Chesterfield) in 1980. But not every area of the county saw growth.

Geography

The Salt Lake Valley is fed by seven streams from the surrounding mountains. All the runoff water eventually ends in the Great Salt Lake, which has no outlet. The mountains rise precipitously from the relatively flat valley surfaces, indicating their comparatively youthful formation. The county has a total area of , of which is land and (8.1%) is water. It is the fifth-smallest county in Utah by area. The county borders on the

The western portion of the county descends toward the valley of the lake, but perhaps the most dominating physical feature in Salt Lake County is the Wasatch Mountains in the eastern portion of the county, famous for both summer and winter activities.

s and wildfires (due to dry lightning and powerful winds). Precipitation is heaviest in late fall/early winter and in spring, while early summer is the driest season. Annual snowfall in the valley is 55 inches (140 cm), with up to 100 inches (250 cm) on the benches. The most snow falls between mid-November and late March. The mountains receive up to 500 inches (1270 cm) of light, dry snow and up to 55 inches (140 cm) of precipitation annually. The dry snow is often considered good for skiing, contributing to the four ski resorts in the county. Snow usually falls from October through May. The heavy snow totals across the county can be attributed to the lake-effect, where precipitation is intensified by the warm waters of the Great Salt Lake, which never entirely freezes due to the lake's high salinity. The lake effect can affect any area of the county, depending on wind conditions. The dry snow is attributed to the low humidity of the region. During winter, temperature inversions are common, causing air pollution in the valley. They trap pollutants, moisture, and cold temperatures in the valley while the surrounding mountains enjoy warm temperatures and clear skies. This can cause some melting snow in the mountains and unhealthy air quality, and low visibility in the valley. This weather event lasts from a few days to a month in extreme cases and is caused when an area of high-pressure over the

Economy

The region's economy used to revolve around LDS services and mining. While both are still important to the economy, each has greatly declined in significance since the 19th century. Since World War II, defense industries in the region have also played a very important role in the economy due to its strategic central location in the Western United States, as well as the largely uninhabited and desolate Great Salt Lake Desert to the west (used for training, weapons testing, and storage of hazardous materials). Beginning in 1939, with the opening of Alta Ski Area, skiing and other winter sports (as well as summer sports), have become a major force in the economy. In 1995, Salt Lake City won the bid to host the
