Mount Rubidoux

Mount Rubidoux is a mountain just west of the city of Riverside, California, United States, that has been designated a city park and landmark. The mountain was once a popular Southern California tourist destination and is still the site of the oldest outdoor non-denominational Easter Sunrise service in the United States. Many historic markers and memorials have been placed on the mountain, the most prominent being the cross at the summit dedicated to Father Junípero Serra.The Santa Ana River flows at the base of the mountain, marking the boundary between the city of Riverside and the Rubidoux neighborhood of the ttc City of Jurupa Valley.The mountain was named for Louis Rubidoux, who established Rancho Rubidoux in 1847, after purchasing a portion of the Rancho Jurupa from Benjamin Davis Wilson, the second elected mayor of Los Angeles.HistoryTom Patterson, as well as most local Riverside historians, have concluded that the original name of Mount Rubidoux was Pachappa. They speculate that one of the early owners of Rancho Jurupa reassigned the name Pachappa to another, smaller hill, in order to expand the property of the Rancho. Since Pachappa hill was designated as the southeast marker of the Jurupa Rancho, which was granted by the Mexican government to Juan Bandini in 1838, reassigning the name to the current Pachappa Hill would have expanded the Rancho Jurupa significantly, incorporating all of the area covered by today's downtown Riverside. It is also possible the United States government renamed the hills in order to satisfy acreage requirements of the original Mexican land Grant.
