Grinding Rock

Chaw’se is the Miwok word for grinding rock – a broad slab of stone where the Miwok people ground acorns and other seeds into meal. The continuous grinding eventually created the cup-shaped depressions in the stone that you see today. Along with the mortar holes, the main grinding rock within the park also features a number of decorative carvings: circles, spoked wheels, animal and human tracks, wavy lines, etc. Some of these carvings are thought to as much as two or even three thousand years old and are now becoming difficult to see. This association of rock art and bedrock mortar pits is unique in California. Except for one other small site, Chaw’se has the only known occurrence of mortars intentionally decorated with petroglyphs.

Native American Craft Demonstrations

On the second Saturday of every month you can watch as Native American Jack Flores performs traditional craft making skills such as basket weaving and flint knapping. Please call the museum for more information.

Native American Ceremonies

Several times a year Native American ceremonies are held in the roundhouse. One of the most important of these is Big Time, a gathering of Indian families on the weekend after the fourth Friday in September. Spectators are welcome to attend. Enjoy dancing, hand games, singing, and storytelling. Indian crafts and foods are available. (Please ask permission before taking pictures of Native Americans.)

Picnic Areas

At Indian Grinding Rock State Park there are both family picnic sites and a group site. A group picnic area with a shade ramada near the grinding rock can accommodate large groups (up to 150 persons). Reservations for the area are not accepted. A small family-type picnic area is located next to the museum.
