Salt Lake Valley is a valley in Salt Lake County in the north-central portion of the U.S. state of Utah. It contains Salt Lake City and many of its suburbs, notably Murray, Sandy, South Jordan, West Jordan, and West Valley City; its total population is 1,029,655 as of 2010. Brigham Young said, "this is the right place," when he and his fellow Mormon settlers moved into Utah after being driven out of several states. Geography The Valley is surrounded in every direction except the northwest by steep mountains that at some points rise from the valley floor's base elevation. It lies nearly encircled by the Wasatch Mountains on the east, the Oquirrh Mountains on the west, Traverse Ridge to the south and the Great Salt Lake on the northwest, with the peaks of Antelope Island visible. Every entrance into the valley is extremely narrow and often congested. They include the Point of the Mountain to the south via the Jordan Narrows, a gap in the Traverse Mountains, narrow entrances between the Great Salt Lake and Oquirrh Mountains to the northwest and the Great Salt Lake and the Wasatch Mountains to the north, and several canyons to the east including Parley's Canyon and Emigration Canyon. Flowing from Utah Lake in Utah Valley in the south, the Jordan River runs north through a gap in the Traverse Mountains, bisecting the Valley before emptying into the Great Salt Lake. The Jordan River, along with numerous mountain streams and reservoirs, provides irrigation water to the rapidly growing Valley. The geography of the Salt Lake Valley combined with the prevalence of industrial pollution and to some extent, fossil fuel burning vehicles, leads to poor air quality in Utah. Development The only areas that have not been urbanized in Salt Lake Valley are near the Great Salt Lake (prevented by frequent flooding) and in the far west and mid-southwest parts of the Valley, although even those areas are beginning to experience the effects of the Salt Lake City urban area's rapid expansion. This southwestern expansion is typified and will be facilitated by the Mountain View Corridor. Some experts are claiming that the Valley will be urbanized rim-to-rim within the next 50 years. A company known as Kennecott Land, which owns the eastern foothills of the Oquirrhs in the western part of the valley, recently drafted a plan that would develop the rest of the entire valley
