"Las Vegas culture" is the name given to many Archaic settlements which flourished between 8000 BCE and 4600 BCE.(10,000 to 6,600 BP) near the coast of present-day Ecuador. The name comes from the location of the most prominent settlement, Site No. 80, near the Las Vegas River and now within the city of Santa Elena. The Las Vegas culture represents "an early, sedentary adjustment to an ecologically complex coastal environment." The Las Vegas culture is important because it was one of the earliest cultures in South America to practice agriculture.
