Welcome to the Chaw'se
Indian Grinding Rock Association

The Chaw'se Indian Grinding Rock Association is a not-for-profit, all-volunteer organization supporting Indian Grinding Rock State Historic Park, one of the most important Native American historic sites in California.

Indian Grinding Rock State Historic Park, located in Northern California's Sierra Nevada foothills, is known for its unique chaw'se (grinding rock), decorated with petroglyphs. The park also features a ceremonial roundhouse, a reconstructed village, picnic grounds, trails, and camping facilities.

The onsite Chaw'se Regional Indian Museum features technology and crafts of the Miwok and other Sierra Nevada Native American groups. The museum also houses a gift shop and bookstore.

Throughout the year, events and ceremonies are held in the roundhouse and on park grounds by local Native Americans, featuring dancing, hand games, singing, storytelling, Native American crafts, guided park tours, and food. These events are open to the public.

At Indian Grinding Rock State Historic Park, we offer group tours for students and adults. Join us to learn more about Miwok life, past and present.
