The area of present-day Canoga Park was the homeland of Native Americans in the Tongva-Fernandeño and Chumash-Venturaño tribes, that lived in the Simi Hills and along to the tributaries of the Los Angeles River. They traded with the north Valley Tataviam-Fernandeño people. Native American civilizations inhabited the Valley for an estimated 8,000 years. Their culture left the Burro Flats Painted Cave nearby.
