This museum and site shows the life of the Miwok and their culture dating back to the Stone Age. There is both an indoor and outdoor component of your visit. The indoor is a typical museum with information and artifacts. The outdoor part of this site is the petroglyphs and grinding rocks, with a reconstructed hut (not sure if that is year-round). Tours of the grinding rock area are available at limited dates and times. Throughout the year they do storytelling and campfires in the evening. Overall, Roseville is lucky to have such a great museum and site.
