Mold Testing in Camarillo, CA

At the time of European contact in the 18th century, Camarillo had been inhabited by the Chumash Indians for thousands of years.

Present day Camarillo and the larger Oxnard Plain were portions of a paramount Chumash capital at the village of Muwu (today’s Point Mugu). Simo’mo (CA-VEN-24), which translates to “the saltbush patch”, was a Chumash village located upstream from Mugu Lagoon near the city of Camarillo. Caves with ancient pictographs are located in the area around Conejo Grade including a site used for religious ceremonies dating back to 500 A.D., where two Chumash villages were located: Lalimanux (Lalimanuc or Lalimanuh) and Kayɨwɨš or Kayiwish (Kawyis) (CA-VEN-243). The village of Kayɨwɨš (Chumash: “The Head”) was first encountered by Europeans of the first Portola expedition on August 16, 1795.

By the early 1820s, Mexico had gained independence from Spain, and shortly afterward California allied itself with Mexico. The Mexican land grant system was liberalized in 1824, resulting in many large grants in California and the proliferation of Ranchos north of the border. One grant to José Pedro Ruiz created Rancho Calleguas in 1837, in the area that is now Camarillo. The grant was later sold to Juan Camarillo, who had arrived in 1834 as a member of the Híjar-Padrés colony; his sons, Adolfo and Juan, began developing a ranch on the Pleasant Valley area of the vast fertile Oxnard Plain.
