Summary

Description	English: Las Vegas at night. (North is to the right of the picture.) The surrounding darkness of the desert presents a stark contrast to the brightly lit street grid of the developed area. The Vegas Strip is reputed to be the brightest spot on Earth due to the concentration of lights on its hotels and casinos. The tarmac of McCarran International Airport is dark by comparison, while the airstrips of Nellis Air Force Base on the north-eastern fringe are likewise dark. The dark mass of Frenchman Mountain borders the city to the east.
