Bellagio

Bellagio is a hotel and casino located on the Las Vegas Strip in the unincorporated area of Paradise in Clark County, Nevada, USA and a member of The Leading Hotels of the World. It is owned by MGM Resorts International and was built on the site of the demolished Dunes hotel and casino.

Inspired by the Lake Como resort of Bellagio in Italy, Bellagio is famed for its elegance. One of its most notable features is an 8-acre (3.2 ha) lake between the building and the Strip, which houses the Fountains of Bellagio, a large dancing water fountain synchronized to music.

Inside Bellagio, Dale Chihuly's Fiori di Como, composed of over 2,000 hand-blown glass flowers, covers 2,000 sq ft (190 m²) of the lobby ceiling. Bellagio is home to Cirque du Soleil's aquatic production "O".

The main (original) tower of the Bellagio, with 3,015 rooms, has 36 floors and a height of 508 ft (151 m). The Spa Tower, which stands to the south of the main tower, has 33 floors, a height of 392 ft (119 m), and contains 935 rooms.

Bellagio was conceived by Steve Wynn and built by his company, Mirage Resorts, Inc. following the purchase and demolition of the legendary Dunes hotel and casino in 1993. Bellagio was designed by DeRuyter Butler and Atlandia Design.

The Bellagio opened October 15, 1998, just before 11 p.m. in a ceremony that was reported to cost US$88 million. The VIPs invited to the grand opening were expected to donate to TheFoundation Fighting Blindness US$1,000 a person or US$3,500 a couple, which entitled them to an overnight stay at Bellagio's suite rooms.

Opening night's entertainment began with Steve Wynn giving a 40-minute welcome speech followed by the opening of the Cirque du Soleil production "O." Performing in Bellagio lounges that night were New York cabaret and recording artist Michael Feinstein, George Bugatti and John Pizarrelli. When it opened, it was the most expensive hotel ever built.

In 2000 it became an MGM Mirage property when Mirage Resorts merged with MGM Grand Inc. to create MGM Mirage. In 2010 the company was renamed MGM Resorts International in a move to go worldwide with its brands.

The Bellagio employs approximately 10,000 people. In the fall of 2006, the casino floor was remodeled and new uniforms were issued, changing the original color scheme to a more elegant type.

Volcano

The Volcano at The Mirage is igniting Las Vegas once again.

Since its opening in 1989, the volcano has been one of most popular attractions on the Strip. In 1996, the volcano added new water, lighting and sound effects.

Today, the volcano is looking - and sounding - better than ever thanks to a $25 million redesign, which reopened to the public on Dec. 8, 2008.

WET, the company responsible for The Fountains of Bellagio, led the design team for the volcano. The volcano includes two volcano systems, a lagoon and fire shooters that shoot flame on demand. These massive fireballs are capable of shooting more than 12 feet into the air. It also features waterfalls with surrounding pools including fire and smoke effects.

"The Mirage Volcano is the only complimentary attraction on The Strip that combines fire with music and choreography," said Scott Sibella, president and COO of the Mirage. "The Mirage Volcano combines the two to create an intense display, both beautiful and thrilling at the same time."

Thanks to WET's state- of-the-art computer system, visitors are able to watch the massive fireballs move to the rhythm. "Using our software VirtualWET, I am able to visually compose the activities of the volcano," Bonnie Thompson, designer and choreographer for WET explained. "That information is then downloaded to our panels that control the fountain and plays according to schedule. Most people don't realize that we can control the movements of the fire and water to create a unique and one-of-a- kind show."

Thompson's vision for the volcano's fireball choreography comes from her fascination by the overall history of the volcano and the culture surrounding it.

Street Strip

The first casino to be built on Highway 91 was the Pair-o-Dice Club in 1931, but the first on what is currently the Strip was the El Rancho Vegas, opening on April 3, 1941, with 63 rooms. That casino stood for almost 20 years before being destroyed by a fire in 1960. Its success spawned a second hotel on what would become the Strip, the Hotel Last Frontier, in 1942. Organized crime figures such as New York's Bugsy Siegel took interest in the growing gaming center leading to other resorts such as the Flamingo, which opened in 1946, and the Desert Inn, which opened in 1950. The funding for many projects was provided through the American National Insurance Company, which was based in the then notorious gambling empire of Galveston, Texas.^[7][8]

Several decades ago, Las Vegas Boulevard South was called Arrowhead Highway, or Los Angeles Highway. The Strip was reportedly named by Los Angeles police officer Guy McAfee, after his hometown's Sunset Strip.^[9]

In 1968, Kirk Kerkorian purchased the Flamingo and hired Sahara Hotels Vice President Alex Shoofey as President. Alex Shoofey brought along 33 of Sahara's top executives. The Flamingo was used to train future employees of the International Hotel, which was under construction. Opening in 1969, the International Hotel, with 1,512 rooms, began the era of mega-resorts. The International is known as the Las Vegas Hilton today.

The first MGM Grand Hotel and Casino, also a Kerkorian property, opened in 1973 with 2,084 rooms. At the time, this was one of the largest hotels in the world by number of rooms. TheRossiya Hotel

The Wet 'n Wild water park opened in 1985 and was located on the south side of the Sahara hotel. The park closed at the end of the 2004 season and was later demolished.

The opening of The Mirage in 1989 set a new level to the Las Vegas experience, as smaller hotels and casinos made way for the larger mega-resorts. These huge facilities offer entertainment and dining options, as well as gambling and lodging. This change affected the smaller, well-known and now historic hotels and casinos, like The Dunes, The Sands, the Stardust, and the Sahara.

In 1995, following the death of Dean Martin, the lights along the Strip were dimmed in a sign of respect to him. This was repeated in 1998 in honor of the recently deceased Frank Sinatra. In 2005, Clark County renamed a section of Industrial Road (south of Twain Avenue) as Dean Martin Drive, also as a tribute to the famous Rat Pack singer, actor, and frequent Las Vegas entertainer.

In an effort to attract families, resorts offered more attractions geared toward youth, but had limited success. The (current) MGM Grand opened in 1993 with Grand Adventures amusement park, but the park closed in 2000 due to lack of interest. Similarly, in 2003 Treasure Island closed its own video arcade and abandoned the previous pirate theme, adopting the new ti name.^[10]

In addition to the large hotels, casinos and resorts, the Strip is home to a few smaller casinos and other attractions, such as M&M World,Adventuredome

In 2004, MGM Mirage announced plans for Project CityCenter, a 66-acre (27 ha), $7 billion multi-use project on the site of the Boardwalk hotel and adjoining land. It consists of hotel, casino, condo, retail, art, business and other uses on the site. City Center is currently the largest such complex in the world. Construction began in April 2006, with most elements of the project opened in late 2009.

Grand Canyon

Though the Grand Canyon isn’t exactly close to Las Vegas, it is arguably the nearest must-see-in-your-lifetime site to the city. As a result, thousands of visitors make an attempt to squeeze in a trip to the Grand Canyon when they visit Las Vegas, especially if they’re in town for three days or more.

The Grand Canyon is a massive fissure in the ground, and, as such, you can’t visit both sides in a single day. In fact, visitors can check out the West Rim, South Rim or North Rim, but each offers its own challenges and considerations. For many, popping into the park and peeking over the edge is more than sufficient, but for others, a longer stay offers an opportunity to explore hiking trails and admire the canyon from a variety of angles.

The West Rim is the most logical point of entry for the Grand Canyon if you’d like to take a day trip. Located approximately 125 miles away from Las Vegas, this tightly regulated part of the Grand Canyon has strict guidelines regarding visitation. Nonetheless, its manageable location makes it a popular destination for visitors to Las Vegas.

When people think of the Grand Canyon, chances are it is the South Rim that comes to mind. Located in Grand Canyon National Park, the South Rim receives 90% of the park’s visitors every year, which means it has the potential to become incredibly crowded. Nonetheless, many people argue that the best views of the Grand Canyon can be found here.

While 90% of the visitors to the Grand Canyon are crowded onto the South Rim, the remaining 10% are enjoying the peace and quiet offered by the North Rim. Though some people say the views of the South Rim far outweigh what is found on the North Rim, many people who have visited the North Rim say they’d never go back to the South Rim after discovering a more peaceful way to explore this natural wonder.

Lake Mead

Lake Mead is the largest reservoir in the United States in maximum water capacity. It is located on the Colorado River about 30 mi (48 km) southeast of Las Vegas, Nevada, in the states of Nevada and Arizona. Formed by water impounded by the Hoover Dam, it extends 112 miles (180 km) behind the dam, holding approximately 28,500,000 acre feet (35.2 km³) of water.

Lake Mead was named after Elwood Mead (1858–1936), who was the commissioner of the U.S. Bureau of Reclamation from 1924 to 1936 during the planning and construction of the Boulder Canyon Project that created the dam and lake. Lake Mead was established as the Boulder Dam Recreation Area in 1936, administrated by the National Park Service. It was then changed to theLake Mead National Recreation Area in 1964, this time including Lake Mohave and the Shivwits Plateau under its jurisdiction. Both lakes and the surrounding area offer year-round recreation options. The accumulated water from Hoover Dam forced the evacuation of several communities, most notably St. Thomas, Nevada, whose last resident left the town in 1938. The ruins of St. Thomas are sometimes visible when the water level in Lake Mead drops below normal.

At lower water levels, a high-water mark or "bathtub ring" is visible in photos that show the shoreline of Lake Mead. The bathtub ring is white because of the deposition of minerals on previously submerged surfaces.

Lake Mead's water level has fallen below the drought level (1125 feet above sea level) three times. From 1953 to 1956, the water level fell from 1,200 to 1,085 feet (370 to 331 m). From 1963 to 1965, the water level fell from 1,205 to 1,090 feet (367 to 330 m). Since 2000 through 2008, the water level has dropped from 1215 to 1095. In 2009 the water level rose slightly due to cool winter temperatures and rainfall.

In June 2010, the lake was at 39 percent of its capacity, and on Nov. 30, 2010 it reached 1,081.94 ft (329.78 m), setting a new record monthly low.^[6] From mid May 2011 to September 22, 2011, Lake Mead's water elevation increased from 1095.5 feet to 1115.24 feet, and the rivers feeding it were running at 128.06% of the average flow rate for September 22.

Lake Mead draws a majority of its water from snow melt in the Colorado, Wyoming, and Utah Rocky Mountains. Since 2000 the water level has been dropping at a fairly steady rate due to less than average snowfall. As a result, marinas and boat launch ramps have either needed to be moved to another part of the lake or have closed down completely. The Las Vegas Bay Marina and the Lake Mead Marinas were relocated a few years ago to Hemenway Harbor. Overton Marina has been closed due to low levels in the northern part of the Overton Arm. Government Wash, Las Vegas Bay, and Pearce Ferry boat launch ramps have also been closed. The marinas that remain open include Las Vegas Boat Harbor and Lake Mead Marina all sharing Hemenway Harbor/Horsepower Cove, Callville Bay Marina, Echo Bay Marina, and Temple Bar Marina, along with the Boulder Launch Area (former location of the Lake Mead Marina) and the South Cove launch ramp.

Changing rainfall patterns, climate variability, high levels of evaporation, reduced snow melt runoff, and current water use patterns are putting pressure on water management resources at Lake Mead as the population depending on it for water and the Hoover Dam for electricity continues to grow. A 2008 paper in Water Resources Research states that at current usage allocation and projected climate trends, there is a 50% chance that live storage in lakes Mead and Powell will be gone by 2021, and that the reservoir could drop below minimum power pool elevation of 1,050 feet (320 m) as early as 2017. Lake volume is now at the mercy of a cascade of forces that include the fact that it is very likely impossible that the prevailing climate pattern of profound drought will or can change to precipitation surcharge in a time frame shorter than that in which the lake level will fall below the dead storage level of the downstream diversion and hydro-power intake tunnels. However, water levels in the lake rose by more than 30 ft (9.1 m) in 2011 due to a rainy winter and increased snowfall in the Rocky Mountains.^[8]

The diversion tunnels, used during construction, are at an elevation at which the flow of the river would continue indefinitely. But they were permanently sealed with massive concrete plugs, isolating them from the remaining sections of the downstream outlet tunnels when the main dam began to be raised and, later when the lake was filled. Today, it is not very likely that they could be removed from the diversion tunnels. And in doing so, it would effectively be the admission that the Hoover Dam project was finished, and had been terminated unsuccessfully. But, Terry Fulp, manager of the federal bureau office for the lower Colorado, disagreed with the paper, saying that global climate models were not sensitive or refined enough to forecast such effects.

Hoover Dam

Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the US states of Arizona and Nevada. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was controversially named in honor of President Herbert Hoover.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and the lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, and is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 25 mi (40 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. Heavily travelled U.S. 93 ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

River diversion

Before the dam could be built, the Colorado River needed to be diverted away from the construction site. To accomplish this, four diversion tunnels were driven through the canyon walls, two on the Nevada side and two on the Arizona side. These tunnels were 56 feet (17 m) in diameter. Their combined length was nearly 16,000 ft or more than 3 mi (5 km). The contract required these tunnels to be completed by October 1, 1933, with a $3,000 per day fine to be assessed for any delay. To meet the deadline, Six Companies had to complete work by early 1933, since only in late fall and winter was the water level in the river low enough to safely divert.

Tunneling began at the lower portals of the Nevada tunnels in May 1931. Shortly afterward, work began on two similar tunnels in the Arizona canyon wall. In March 1932, work began on lining the tunnels with concrete. First the base, or invert, was poured. Gantry cranes, running on rails through the entire length of each tunnel were used to place the concrete. The sidewalls were poured next. Movable sections of steel forms were used for the sidewalls. Finally, using pneumatic guns, the overheads were filled in. The concrete lining is 3 ft (1 m) thick, reducing the finished tunnel diameter to 50 ft (15 m) The river was diverted into the two Arizona tunnels (the Nevada tunnels were kept in reserve for high water) on November 13, 1932. This was done by exploding a temporary cofferdam protecting the Arizona tunnels while at the same time dumping rubble into the river until its natural course was blocked.

Following the completion of the dam, the entrances to the two outer diversion tunnels were sealed at the opening and halfway through the tunnels with large concrete plugs. The downstream halves of the tunnels following the inner plugs are now the main bodies of the spillway tunnels.

Environmental impact

The changes in water use caused by Hoover Dam's construction has had a large impact on theColorado River Delta. The construction of the dam has been credited as causing the decline of this estuarine ecosystem. For six years, after the construction of the dam and while Lake Mead filled, virtually no water reached the mouth of the river. The delta's estuary, which once had a freshwater-saltwater mixing zone stretching 40 miles (64 km) south of the river's mouth, was turned into an inverse estuary where the level of salinity was higher close to the river's mouth.

The Colorado River had experienced natural flooding before the construction of the Hoover Dam. The dam eliminated the natural flooding, which imperiled many species adapted to the flooding, including both plants and animals. The construction of the dam devastated the populations of native fish in the river downstream from the dam. Four species of fish native to the Colorado River, the Bonytail chub, Colorado pikeminnow, Humpback chub, and Razorback sucker, are currently listed as endangered.

Naming controversy

During the years of lobbying leading up to the passage of legislation authorizing the dam in 1928, the dam was generally referred to by the press as "Boulder Dam" or "Boulder Canyon Dam", notwithstanding the fact that the proposed site had been shifted to Black Canyon. The Boulder Canyon Project Act of 1928 (BCPA) never mentions a proposed name or title for the dam. The BCPA merely allows the government to "construct, operate, and maintain a dam and incidental works in the main stream of the Colorado River at Black Canyon or Boulder Canyon".

When Secretary Wilbur spoke at the ceremony starting the building of the railway between Las Vegas and the dam site on September 17, 1930, he named the dam "Hoover Dam", citing a tradition of naming dams after Presidents, though none had been so honored during their terms of office. Wilbur justified his choice on the ground that Hoover was "the great engineer whose vision and persistence ... has done so much to make [the dam] possible". One writer complained in response that "the Great Engineer had quickly drained, ditched, and dammed the country".

After Hoover's election defeat and the accession of the Roosevelt administration, Secretary Ickes ordered on May 13, 1933 that the dam be referred to as "Boulder Dam". Ickes stated that Wilbur had been imprudent in naming the structure after a sitting president, that Congress had never ratified his choice, and that it had long been referred to as Boulder Dam. When Ickes spoke at the dedication ceremony on September 30, 1935, he was determined, as he recorded in his diary, "to try to nail down for good and all the name Boulder Dam"At one point in the speech, he spoke the words "Boulder Dam" five times within thirty seconds. Further, he suggested that if the dam were to be named after any one person, it should be for California Senator Hiram Johnson, a lead sponsor of the authorizing legislation. Roosevelt also referred to the dam as Boulder Dam, and the Republican-leaning Los Angeles Times, which at the time of Ickes' name change had run an editorial cartoon showing Ickes ineffectively chipping away at an enormous sign "HOOVER DAM", reran it showing Roosevelt reinforcing Ickes, but having no greater success.

In the following years, the name "Boulder Dam" failed to fully take hold, with many Americans using the two names interchangeably and mapmakers divided as to what name should be printed. Memories of the Great Depression faded, and Hoover to some extent rehabilitated himself through good works during and after World War II. In 1947, a bill passed both Houses of Congress unanimously restoring the name to "Hoover Dam". Ickes, who was by then a private citizen, opposed the change, stating, "I didn't know Hoover was that small a man to take credit for something he had nothing to do with."
