Simi Valley was once inhabited by the Chumash people, who also settled much of the region from the Salinas Valley to the Santa Monica Mountains, with their presence dating back 10,000–12,000 years. Around 5,000 years ago these tribes began processing acorns, and harvesting local marshland plants. Roughly 2,000 years later, as hunting and fishing techniques improved, the population increased significantly. Shortly after this sharp increase a precious stone money system arose, increasing the viability of the region by offsetting fluctuations in available resources relating to climate changes. The native people who inhabited Simi Valley spoke an interior dialect of the Chumash language, called Ventureño.
