paragraph_text: The Golden Nugget was originally built in 1946, making it one of the oldest casinos in the city. Jackie Gaughan at one time owned a stake in the hotel as part of his many downtown properties. Steve Wynn bought a stake in the Nugget, which he increased so that, in 1973, he became the majority shareholder, and the youngest casino owner in Las Vegas. In 1977 he opened the first hotel tower and the resort earned its first four diamond rating from Mobil Travel Guide. It was the foundation for Wynn's rise to prominence in the casino industry. The second hotel tower opened in 1984 along with the showroom, and the third tower was opened in 1989. In 2000, the Golden Nugget (and all of Mirage Resorts' other properties) was sold to MGM Grand, Inc. (later named MGM Mirage).

paragraph_text: The Humboldt Range is a largely north-south running range of mountains in northwest Nevada, USA, that extend from the town of Imlay in the north to the junction with the West Humboldt Range in the south. It is bordered continuously by Interstate 80 and the Humboldt River, largely expanded in the form of the Rye Patch Reservoir in this area, on the west side and by a long and fairly broad Buena Vista Valley to the east, in a typical basin-and-range pattern. The Humboldts are ostensibly visible to travelers along Interstate 80, especially with respect to the highest point of the range, Star Peak, which with a quite nicely defined tip reaches an elevation of 9,836 feet (2,998 m), located in the center of the north range section. The midpoint of the range is in the area of Fourth of July Flat. The Humboldt Range is also noteworthy for having a famous historical town at its base on the eastern side called Unionville, which, for a brief period, was home to Samuel Clemens. Another historical site, now a ghost town, nearby is called Star City. Unlike some ranges in the vicinity, the substantial height of the Humboldts allows for a number of continuously flowing watersheds, and hiking the terrain is a somewhat noted activity.
