The Upper Las Virgenes Canyon Open Space Preserve is a large open space nature preserve owned and operated by the Santa Monica Mountains Conservancy spanning nearly in the Simi Hills of western Los Angeles County and eastern Ventura County.Originally part of Ahmanson Ranch, this area was sold by Seattle-based Washington Mutual to the Santa Monica Mountains Conservancy in late 2003 after lengthy issues concerning development in the chaparral shrub forest and oak savanna understory and overstory Plant communities. It was previously called Ahmanson Ranch Park.HistoryPre-1963For thousands of years the Chumash Native American tribe lived in the current Preserve's area. The Chumash had, prior to European involvement, at least one village on the land, Huwam, a multi-cultural village where Chumash, Tongva, and Tataviam peoples lived. On Bell Creek beside Escorpión Peak (Castle Peak) a large rocky mountain on the property of El Escorpion Park, is the reported site of this village. The peak is one of nine alignment points in Chumash territory and is essential to maintaining the balance of the natural world. A cave known as The Cave of Munits exists just inside the property. This is the believed cave of a mythical Chumash shaman who was killed after murdering the son of a Chumash chief.
