which means "place of the old woman") and Topanga (in Tongva, , and in Fernandeño, Tupá’nga, with a root topaa’-/tupá’- that likely comes from Ventureño). The Tataviam were established in the valleys to the north; Pacoima (Fernandeño: pakoinga or pakɨynga) is believed to be of Tataviam-Fernandeño people's Tataviam language origin and means the entrance in the Fernandeño dialect. The Hokan-speaking Chumash people inhabited Malibu, the Santa Monica Mountains, and the Simi Hills in the western area of the Valley, and much of the coastal areas to the northwest. At Bell Creek below the rocky outcropping called Escorpión Peak (Castle Peak), Chumash pictographs and other artifacts have been identified by archeologists at a site, Hu'wam, which is thought to have been a meeting place and trading center for the Tongva-Fernandeño and Chumash-Venturaño. In the Simi Hills the Burro Flats Painted Cave pictographs are located on Rocketdyne's Santa Susana Field Laboratory property, inaccessible but well protected. The Tataviam-Fernandeño people inhabited the foothills of the Santa Susana Mountains in the Valley (and north in the Santa Clara River area). The Tongva-Fernandeño inhabited the Valley, along the tributaries to the Los Angeles River. Exploration In 1769, the expedition led by explorer Gaspar de Portolà reached the Los Angeles area of California overland from Baja California. Accompanying him were two Franciscan Padres, Junípero Serra and Juan Crespí, who recorded the expedition and identified locations for a proposed network of missions, along which the royal highway (El Camino Real) was eventually built. After camping at and naming the location that would become the Pueblo de Los Angeles, the expedition proceeded westward before turning north through the Sepulveda Pass over the Santa Monica Mountains on the feast day of Saint Catherine of Bologna. The watering place was a pool fed by a perennial spring at what is now Encino, near the village of Siutangna. The name El Valle de Santa Catalina de Bononia de los Encinos refers to the encinos or evergreen Coast Live Oaks that studded the area. The expedition proceeded northward, camping at a site in the northern Valley before crossing over the mountains into the Santa Clarita Valley. Father Crespí had identified a location along the Los Angeles River that would be perfect for a settlement, possibly a mission, but in 1781, King Charles III of Spain ordered that a pueblo be built on the site, which would be the second town in Alta
