The first known inhabitants of Oregon were Paleo-Indians, with the first found settlement dating to about 13,200 years ago, although archaeologists believe that humans lived in the area 15,000 years ago. The first known specific tribes in the area include the Chinook, Bannock, Nez Perce and Umpqua, among others.
The earliest found site of human habitation within the borders of present-day Oregon is called Fort Rock Cave, located near the town of Fort Rock. Some of the earliest human remains were found in an area of south-central Oregon called Paisley Caves. The remains contain DNA linking them to Siberia or Asia. Other tribes found in Oregon include the Coquille, Chasta, Kalapuya, Klamath, Molalla, Takelma and Tillamook.
