Passage:The hills of and immediate foots of the Santa Susana Mountains have been inhabited for thousands of years, proven by Chumash artifacts found by the Santa Susana Depot and Chumash pictographs dating to 500 AD in the Burro Flats Painted Cave. The area has likely been populated by Native-American peoples for as much as 8,000 years-12,000 years ago The Burro Flats Painted Cave, now situated on the protected private Santa Susana Field Laboratory property, was the setting for a winter solstice ritual for the Ventureño Chumash people. The cave, which is on the back wall of a sandstone shelter about 16 ft long and 4 ft high, was discovered at the turn of the 20th century The Chumash of Santa Susana were unlike other settlements in the Simi Valley not only located near other Ventureño Chumash settlements, but the Chumash here traded with the Tataviam people who also settled in the Santa Susana Mountains, as well as the Gabrielino people who inhabited the opposite side of the Santa Susana Pass.
