Question: What two areas are coevered by the Timeline of Las Vegas?
Context: This history of Las Vegas covers both the city of Las Vegas, Nevada, and the Las Vegas Valley. The Las Vegas–Paradise, NV MSA, also known as the Las Vegas–Henderson–Paradise, NV Metropolitan Statistical Area (2013), is in the southern part of the U.S. state of Nevada, coextensive since 2003 with Clark County, Nevada.  A central part of the metropolitan area is the Las Vegas Valley, a 600 sqmi basin that includes the metropolitan area's largest city, Las Vegas as well as the other primary city, Paradise, Nevada.  The area contains the largest concentration of people in the state.  Cities in the metropolitan area include Las Vegas, Henderson, North Las Vegas, and Boulder City.  The metropolitan area is one of the top tourist destinations in the world, drawing over 40 million international and domestic visitors in 2013 with a GMP of US$103.3 billion. Las Vegas Uncork'd (also referred to as Vegas Uncork'd and Vegas Uncorked) is an annual culinary and wine event in Las Vegas, Nevada.  The concept was developed by the Las Vegas Convention and Visitors Authority, their advertising agency R&R Partners and Las Vegas resort partners who originally considered a number of magazine partners such as Bon Appetit, Food & Wine and Gourmet.  Bon Appetit was selected as the magazine partner after a review with each magazine.  The event was launched in 2007 by the Las Vegas Convention and Visitors Authority, "Bon Appétit" magazine led by Editor-in-Chief Barbara Fairchild and co-creator and Executive Director Rob O'Keefe who led the first five years of development of what Eater.com called "the world's most innovative culinary event".  Las Vegas resort partners over the years include Bellagio, Caesars Palace and Wynn Las Vegas, MGM Grand, Mandalay Bay, The Venetian, Las Vegas and The Palazzo and each year the event features more than 80 celebrated chefs and over 25 events occurring over a spectacular four-day weekend. The following is a of the history of the city of Las Vegas, Nevada, United States. Sloan is an unincorporated community with a population of 105 (as of the U.S. Census 2010) in Clark County, Nevada, situated 18 miles southwest of Las Vegas.  It is named for its limestone dolomite carnotite and was first settled in 1912 under the name Ehret, NV; named for the founders family name, but changed its name to Sloan on September 11, 1922.  It is known for its canyon and its Sloan Canyon Petroglyph Site, Petroglyph Canyon, Black Mountain, and is mostly located within the North McCullough Wilderness Area and is adjacent to the McCullough Range.  It contains well-preserved petroglyphs and several hiking trails that allow visitors to photograph the petroglyphs.  Sloan is also home to the George W. Dunaway Army Reserve Center which officially opened in April 2015, which is a large military area not open for public.  2.7 miles west of Sloan was the site of the Bonanza Air Lines Flight 114 accident, which killed 29 people.  Most of the residential areas are located on the main street, Sloan Road, and other smaller roads such as Arville Street, Hinston Street, and Roark Avenue.  It is adjacent to the Interstate 15 in Nevada.  To get here from Las Vegas, take Interstate 15 south and take exit 25 at Sloan.  On Las Vegas Boulevard, turn right for the residential areas and George W. Dunaway Army Reserve Center, while turn left and follow Las Vegas Boulevard for 0.1 mile to reach the road leading to Sloan Canyon National Conservation Area.  Following the power line road is treacherous.  A faster, safer, and brand new paved road through the Henderson neighborhood of Anthem takes you to the Sloan Canyon visitors center and trailhead to the Petroglyphs. Air Vegas (IATA: 6V, ICAO: VGA, Call sign: Air Vegas) was an airline with its headquarters on the grounds of the North Las Vegas Air Terminal in North Las Vegas, Nevada.  It operated daily sightseeing flights from Las Vegas to the Grand Canyon.  Prior to moving to the North Las Vegas Airport its main bases were McCarran International Airport (LAS), Las Vegas and Henderson Executive Airport (HND), Las Vegas. The Oakland Raiders relocation to Las Vegas was a successful effort by the owner of the Oakland Raiders (Mark Davis) to relocate the American football club from its current and longtime home of Oakland, California to Las Vegas, Nevada.  The team is scheduled to begin play as the Las Vegas Raiders for the 2020 National Football League (NFL) season (although a move to Las Vegas could happen as soon as 2019 with Sam Boyd Stadium), playing home games at the Las Vegas Stadium.  NFL team owners voted 31–1 to approve the move, which was announced at the annual league meetings in Phoenix, Arizona on March 27, 2017.  The Raiders became the third NFL franchise to relocate in the 2010s, following the Rams' move from St. Louis, Missouri to Los Angeles, California on January 12, 2016, and the Chargers' move from San Diego, California to Los Angeles on January 12, 2017.  The Raiders' move to Las Vegas comes after years of failed efforts to renovate or replace the Oakland–Alameda County Coliseum, which has been rated by multiple sources as one of the worst stadiums in the NFL. Transportation in the Las Vegas Valley including the cities of Las Vegas, North Las Vegas and Henderson is a multi faceted system.  The street system is mostly laid out in a north-south/east-west system of roads.  While most residents rely on cars, there is an extensive network of bus routes reaching many areas of the county.  The Las Vegas Valley, being the one of the largest tourist destinations in the world, has a mass transportation system which favors the Las Vegas Strip. Robertson High School (RHS) is a public senior high school in Las Vegas, New Mexico.  The school is part of the Las Vegas City Schools District in former East Las Vegas.  The building dates from about 1945, when it was known as Las Vegas High School.  The school was renamed Las Vegas Robertson High School in 1958, after the old Las Vegas High School burned down and a new building was constructed.  W. J. Robertson had been the Superintendent of the Las Vegas City Schools since 1941 when he suffered a fatal heart attack on November 26, 1956 at the age of 55.  Mr. Robertson, born in Kansas on November 3, 1901 also served as Principal at Las Vegas High School for many years prior.  The colors of RHS are red and white, their mascot is the Cardinal.  The enrollment currently stands at 607. The Las Vegas metropolitan area is home to many sports, most of which take place in the unincorporated communities around Las Vegas rather than in the city itself.  The Las Vegas Valley has one major league professional team: the Vegas Golden Knights of the National Hockey League (NHL) who began play in 2017 as the region's first major pro team.  The Oakland Raiders of the National Football League (NFL) will begin play in Las Vegas as the "Las Vegas Raiders" by 2020 and become the region's second major professional team.  Las Vegas is also home to one minor league sports team: the Las Vegas 51s of the Triple-A Pacific Coast League (Minor League Baseball).  The 51s are currently the only team to actually play in the city of Las Vegas, playing at the city owned Cashman Field.  They will be joined in 2018 by the Las Vegas Lights FC of the United Soccer League, one of two leagues that collectively make up the second level of the U.S. men's soccer league system.
