Question: State Route 209 (SR-209) is a state highway in the U.S. state of Utah, following 9000 South and other east–west streets south of Salt Lake City, It connects I-15 in Sandy with the ski areas of Little Cottonwood Canyon, and, once an extension is complete, with which mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah?
Context: The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.  The mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tonnes.  The mine is owned by Rio Tinto Group, a British-Australian multinational corporation.  The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery.  The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 mi deep, 2.5 mi wide, and covering 1,900 acre .  It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine.  The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013. State Street is a wide 17.3 mi street in Salt Lake County, Utah leading almost straight south from the steps of the Utah State Capitol Building, through Salt Lake City (including Downtown Salt Lake City), South Salt Lake, western Millcreek Township, Murray (including the Murray Downtown Historic District), eastern Midvale, Sandy (including the Sandy Historic District and Downtown Sandy), and northwestern Draper.  Because it follows the most direct route from downtown Salt Lake City to the Point of the Mountain pass to Utah County, it was the undisputed main road south from Salt Lake City until Interstate 15 was built to the west (but closely paralleling it).  It retains the US Highway 89 designation for all but the northernmost seven blocks (which are part of State Route 186 instead) despite I-15's proximity.  Due to its history as a route for long-distance travel, travel within the Wasatch Front region, and travel between the cities along the east side of the Jordan River, it has attracted a wide variety of retail and service businesses along its entire length, creating a nearly continuous commercial axis for the Salt Lake Valley. Utah State Route 176 was a state highway in entirely within the cities of Salt Lake City and South Salt Lake in Salt Lake County, Utah, United States.  It mainly functioned as an alternate route for US-89, US-91, and I-15 traffic that provided access to industrial areas of the two cities and avoided urban cross-traffic in Downtown Salt Lake City.  The original route followed 900 South west from State Street (Salt Lake County) (concurrent US-89 and US-91) to 300 West and then traveled north on 300 West to meet US-89 and US-91 again at South Temple (or, later, at North Temple).  The route was subsequently changed to follow 300 West only: it followed 300 West all the way from 3300 South (SR-171) to North Temple (traffic from either I-15 or State Street could reach the southern end along short stretches of SR-171). Solitude Mountain Resort is a ski resort located in the Big Cottonwood Canyon of the Wasatch Mountains, thirty miles southeast of Salt Lake City, Utah.  With 66 trails, 1200 acre and 2047 ft vertical, Solitude is one of the smaller ski resorts near Salt Lake City, along with its neighbor Brighton.  It is a family-oriented mountain, with a wider range of beginner and intermediate slopes than other nearby ski resorts; 50% of its slopes are graded "beginner" or "intermediate," the highest such ratio in the Salt Lake City area.  Solitude was one of the first major US resorts to adopt an RFID lift ticket system, allowing lift lines to move more efficiently while reducing "lift poaching".  It was followed by Alta Ski Area in 2007.  Solitude is adjacent to Brighton Ski Resort near the top of Big Cottonwood Canyon.  Solitude and Brighton offer a common "Solbright Pass" which provides access to both resorts for a nominal surcharge. State Route 201 (SR-201) is an east–west expressway and freeway located in Salt Lake County in the U.S. state of Utah.  Colloquially known as the "21st South Freeway", the route serves as an alternative to Interstate 80 (I-80) through Salt Lake City.  From the western terminus of the route west of Magna, the highway heads east through Kennecott Copper property as an expressway before running through the western suburbs of Salt Lake City as a freeway.  Shortly after the route returns on a surface route, SR-201 terminates on its eastern end at State Street (U.S. Route 89). There are actually two sets of well-known Twin Peaks of the Wasatch Front in Utah.  "Broad's Fork" Twin Peaks, overlooking the Salt Lake Valley, and "American Fork" Twin Peaks which is located less than five miles to the southeast.  "American Fork" Twin Peaks is actually the higher of the two, at 11489 ft , and is the tallest peak of Salt Lake County.  "Broads Fork" Twin Peaks is only 11330 ft and the second highest of Salt Lake County.  While standing atop either one, the other can easily be seen.  American Fork Canyon lies on the southern flank of its Twins with Little Cottonwood Canyon to the north.  Broad's Fork Twins is also flanked by Little Cottonwood Canyon, but to the south and Broad's Fork, a side-canyon of Big Cottonwood Canyon, to the north.  Deaf Smith Canyon and Ferguson Canyon also make their short courses up the western side of Broad's Fork Twin Peaks. State Route 209 (SR-209) is a state highway in the U.S. state of Utah, following 9000 South and other east–west streets south of Salt Lake City.  It connects I-15 in Sandy with the ski areas of Little Cottonwood Canyon, and, once an extension is complete, with the Bingham Canyon Mine. The Unified Police Department of Greater Salt Lake (UPD) is a police department located in Salt Lake County, Utah.  The UPD serves unincorporated Salt Lake County and the communities of Copperton, Herriman, Holladay, Kearns, Midvale, Magna, Millcreek, Taylorsville, and Riverton.  Additionally, Big Cottonwood Canyon, Little Cottonwood Canyon, Parleys Canyon, Emigration Canyon, Lambs Canyon, and Butterfield Canyon are policed by UPD's Canyon Patrol.  The southeast areas of Willow Canyon, White City, Granite, Sandy Hills, and Willow Creek are also within UPD's jurisdiction. Little Cottonwood Creek is one of the principal streams entering Salt Lake Valley from the east rises near the summit of the Wasatch Mountains a short distance south of the ski resort town of Alta and flows in a westerly direction through Little Cottonwood Canyon until it emerges into Salt Lake Valley about eleven miles from its source thence its course is north westerly through Sandy, Midvale and Murray, Utah until it empties into the Jordan River about six miles south of Salt Lake City.  Its whole length is nearly twenty seven miles. State Route 210 is a state route in the U.S. state of Utah that is the access road for Little Cottonwood Canyon and the ski resorts of Alta and Snowbird.  The 13.62 mi (21.92 km) highway straddles the southeastern edge of the Salt Lake Valley before it enters the mouth of Little Cottonwood Canyon.
