The Dalton Period extends from 10,500 to 9,900 radiocarbon years ago (circa 8500 to 7900 BC), during which there existed a culture of ancient Native American hunter-gatherers (referred to as the Dalton people) who made a distinctive set of stone tools that are today found at sites across the middle of the United States. The name Dalton was first used in 1948 to refer to a style of chipped-stone projectile point/knife.
