This Museum displays exhibits illustrating the cultures of the state’s first inhabitants. California’s prehistoric population, one of the largest and most diverse in the Western hemisphere, was made up of over 150 distinct Native groups who spoke at least sixty-four different languages and whose estimated population, before the arrival of Europeans, was at least 500,000 people. California Indian cultural items in the museum include basketry, beadwork, clothing and exhibits about the ongoing traditions of varied California Indian tribes. A section of the museum features a hands-on area that has visitors trying their hand at using Indian tools. Self-guided tours provide an opportunity to celebrate the proud heritage of California Indian culture.
