California Historical Resources

California's historical resources represent the contributions and collective human experiences of a diversified population spanning 10,000-12,000 years of occupancy in California. This rich heritage is embodied in the cultural and historical landscapes of California as evidenced by archaeological remains, historic buildings, traditional customs, tangible artifacts, historical documents, and public records extant in California. All these evidences of the past contribute to the sum total of California's history. Such historical resources provide continuity with our past and enhance our quality of life.
