Utah is a U.S. state located in the western United States. It was the 45th state admitted to the union on January 4, 1896. Approximately 80% of Utah's 2,500,000 people live in a population corridor centered on Salt Lake City, known as the Wasatch Front. In contrast, vast expanses of the state are relatively uninhabited and rural, making Utah the sixth most urbanized state.

The state is generally rocky with three distinct geological regions: the Rocky Mountains, the Great Basin, and the Colorado Plateau. Utah is known for its natural diversity and is home to features ranging from arid deserts with sand dunes to thriving pine forests in mountain valleys.
It has a large tourism business and was host to the 2002 Winter Olympics. The ski resorts in the northern Wasatch Range, the Bonneville Salt Flats, the Great Salt Lake, the five national parks in the south, such as Arches, Zion and Bryce Canyon, and cultural attractions such as Temple Square, Sundance Film Festival, and the Utah Shakespearean Festival are among the most visited.
Approximately 60% of state residents are members of The Church of Jesus Christ of Latter-day Saints (LDS Church), which represent less than 50% of the population in urban areas and over 90% in rural areas. The religion has historically had a strong regional influence and has contributed to the state's restrictive attitude towards alcohol and gambling, while also contributing to its high birth rate (by far the highest in the nation). Before 1890, the Church's teachings of plural marriage had led to confrontation with the U.S. federal government in the Utah War.
Utah is one of the Four Corners states, and is bordered by Idaho and Wyoming in the north; by Colorado in the east; at a single point by New Mexico to the southeast (at the Four Corners Monument); by Arizona in the south; and by Nevada in the west. It covers an area of 84,899 square miles (219,887 km²).
One of Utah's defining characteristics is the variety of its terrain. Running down the center of the state is the Wasatch Range, which rises to heights of about 12,000 feet (3,650 m) above sea level. Portions of these mountains receive more than 500 inches (1,250 cm) of snow each year and are home to world-renowned ski resorts, made popular by the light, fluffy snow, which is considered good for skiing. In the northeastern section of the state, running east to west, are the Uinta Mountains, which rise to heights of 13,000 feet (3,950 m) or more. The highest point in the state, Kings Peak, at an elevation of 13,526 feet (4,123 m), lies within the Uinta Mountains.
At the western base of the Wasatch Range is the Wasatch Front, a series of valleys and basins that are home to the most populous parts of the state. The major cities of Ogden, Salt Lake City, Layton, West Valley City, Sandy, West Jordan, Orem, and Provo are located within this region, which stretches approximately from Brigham City at the north end to Nephi at the south end. Approximately 75% of the population of the state lies in this corridor, and urban sprawl continues to expand along the edges of these valleys.
Western Utah is mostly arid desert with a basin and range geology. Small mountain ranges and rugged terrain punctuate the landscape. However, the Bonneville Salt Flats are an exception, being comparatively flat. Most of western Utah was once covered in Lake Bonneville. The Great Salt Lake and Utah Lake are the only two significant remains of this ancient freshwater lake, which once covered most of the eastern Great Basin. West of the Great Salt Lake, stretching to the Nevada border, lies the Great Salt Lake Desert, the most arid area in Utah.
Much of the scenic southern landscape is sandstone, more specifically Kayenta sandstone and Navajo sandstone. The Colorado River and its tributaries wind their way through the sandstone, creating some of the most striking and wild terrain in the world. Wind and rain have also sculpted the soft sandstone over millions of years. Canyons, gullies, arches, pinnacles, buttes, bluffs, and mesas are the common sight throughout south-central and southeast Utah. This terrain is accentuated in protected parks such as Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion national parks, Cedar Breaks, Grand Staircase-Escalante, Hovenweep, and Natural Bridges national monuments, Glen Canyon National Recreation Area (site of the popular tourist destination, Lake Powell), Dead Horse Point and Goblin Valley state parks, and Monument Valley, a popular photographic and filming site.
Southwestern Utah is the lowest and hottest spot in Utah. It is known as Dixie because early settlers were able to grow limited amounts of cotton there. Beaverdam Wash in far southwestern Utah is the lowest point in the state, at an elevation of 2,000 feet (610 m). The northernmost portion of the Mojave Desert is also located in this area. Dixie is quickly becoming a popular recreational and retirement destination, and the population is growing rapidly. Just north of Dixie is the state's highest ski resort, Brian Head.
Eastern Utah is a high elevation area covered mostly by plateaus and basins. Economies are dominated by mining, oil and natural gas-drilling, ranching, and recreation. Much of eastern Utah is part of the Uintah and Ouray Indian Reservation. The most popular destination within eastern Utah is Dinosaur National Monument.
Like most of the west and southwest states, the federal government owns much of the land in Utah. Over seventy percent of the land is either BLM land or U.S. National Forest, park, U.S. National Monument, National Recreation Area or U.S. Wilderness Area.
Interstate 15 is the main interstate highway in the state, entering from Arizona north to Idaho and serving such cities as St. George, Provo, Salt Lake City, and Ogden. Breaking from Interstate 80 at Echo, Interstate 84 heads northwest through the mountains and out onto the Wasatch Front, merging with I-15 at Roy and staying merged until Tremonton.
I-84 then continues northwestwardly into Idaho near Snowville. I-80 enters Nevada at Wendover and heads east through Salt Lake City, briefly merging with I-15 before climbing into the mountains and weaving through canyons and across plateaus into Wyoming, just before reaching Evanston. Interstate 70 begins at Cove Fort and heads east through mostly uninhabited areas, providing access to many of southern Utah's recreation areas before entering Colorado. The stretch of I-70 between Salina and Green River is the longest stretch of interstate in the nation without any services.
A light rail system in the Salt Lake Valley known as TRAX consists of two lines, one providing access from downtown Salt Lake City and Sandy, and the other providing access to the University of Utah east of downtown. The Utah Transit Authority (UTA) operates a bus system stretching across the Wasatch Front and into Tooele, and also provides winter service to the ski resorts above Salt Lake City.

Several bus companies provide access to the ski resorts in winter, and local bus services also serve Logan, St. George and Cedar City. The Legacy Highway is a controversial freeway that is planned to eventually run down the entire length of the Wasatch Front. The first portion, known as the Legacy Parkway, in southern Davis County, will begin construction in spring 2006. A commuter rail line, named FrontRunner, is under construction between Salt Lake City and Pleasant View, north of Ogden, and will be complete by 2008. FrontRunner is expected to eventually span the Wasatch Front from Brigham City in the north to Payson in the south.

* Most of Utah is arid and high in elevation. Most of eastern and southern Utah receive 12 inches (300 mm) or less of precipitation per year, while many mountain areas receive more than 40 inches (1,000 mm) per year, with some areas receiving up to 60 in (1,500 mm). Much of western Utah receives less than 10 inches (250 mm), while the Wasatch Front receives approximately 15 inches (380 mm).
The Great Salt Lake Desert is especially dry, receiving less than 5 inches (130 mm) annually. Snowfall is common in winter everywhere except the southern border and the Great Salt Lake Desert. St. George averages about 3 inches (7.5 cm) of snow per year, while Salt Lake City receives almost 60 inches (150 cm) annually (amplified by the lake effect from the Great Salt Lake). Many mountain areas receive in excess of 350 inches (900 cm) of snow in a year, while portions of the Wasatch Range receive up to 500 inches (1,250 cm). Snowfall is common from late November through March in the lower elevations and from October through May in the mountains. The mountains often remain snow-covered into July. Fog and haze often caused by temperature inversions are common in the valleys and basins during winter, especially the Uinta Basin, just south of the Uinta Mountains.
During summer and fall, most of the precipitation is received from the storms coming from the south and consists of short, sporadic, and intense thunderstorms that can cause wildfires and flash floods. Most precipitation during the rest of the year is received from the Pacific Ocean. Spring is the wettest season across the north while late summer and early fall are the wettest times in the south and winter is the wettest season in most of the mountain areas.
Temperatures during the winter across much of Utah are below freezing. High temperatures average between 25 °F (-4 °C) and 50 °F (10 °C) across the state. Days below 0 °F (-18 °C) can be expected in many areas at least once a year, but they are usually short in duration and not terribly severe. Mountains to the north and east of the state serve as barriers to Arctic air. In the summer, high temperatures average between 85 °F (29 °C) and 100 °F (38 °C). Days over 100 °F (38 °C) can be expected in most areas below 5,000 feet (1,500 m) at least once per year and are the norm in the southern valleys. The record high temperature in Utah was 117 °F (47 °C), recorded at St. George on July 5, 1985, and the record low was -69 °F (-56 °C), recorded at Peter's Sink in the Bear River Mountains of northern Utah on February 1, 1985.
Beginning in the early 1900s, with the establishment of such national parks as Bryce Canyon National Park and Zion National Park, Utah began to become known for its natural beauty. Southern Utah became a popular filming spot for arid, rugged scenes, and such natural landmarks as Delicate Arch and "the Mittens" of Monument Valley are instantly recognizable to most national residents. During the 1950s, '60s, and '70s, with the construction of the Interstate highway system, accessibility to the southern scenic areas was made easier.
Beginning in 1939, with the establishment of Alta Ski Area, Utah has become world-renowned for its skiing. The dry, powdery snow of the Wasatch Range is considered some of the best skiing in the world. Salt Lake City won the bid for the 2002 Winter Olympics in 1995, and this has served as a great boost to the economy. The ski resorts have increased in popularity, and many of the Olympic venues scattered across the Wasatch Front continue to be used for sporting events. This also spurred the development of the light-rail system in the Salt Lake Valley, known as TRAX, and the re-construction of the freeway system around the city.
During the late 20th century, the state grew quickly. In the 1970s, growth was phenomenal in the suburbs. Sandy was one of the fastest-growing cities in the country at that time. Today, many areas of Utah are seeing phenomenal growth. Northern Davis, southern and western Salt Lake, Summit, eastern Tooele, Utah, Wasatch, and Washington counties are all growing very quickly. Transportation and urbanization are major issues in politics as development consumes agricultural land and wilderness areas.
