Description - Indian Grinding Rock State Historic Park is located in the Sierra Nevada foothills eight miles east of Jackson. The park nestles in a little valley 2,400 feet above sea level with open meadows and large valley oaks that once provided the native Americans of this area with an ample supply of acorns. The 135-acre park was created in 1968 and preserves a great outcropping of marbleized limestone with some 1,185 mortar holes -- the largest collection of bedrock mortars in North America.

An old indian village in Indian Grinding Rock SHP
- Trails make it easy to explore the meadows and surrounding forest. The Chaw'se Regional Indian Museum features a variety of exhibits and an outstanding collection of Sierra Nevada Indian artifacts. A Miwok village complete with roundhouse has been reconstructed in the middle of the valley. The Chaw'se Regional Indian Museum has been designed to reflect the architecture of the traditional roundhouse. Exhibited in this two-story museum are outstanding examples of the technology and crafts of the Miwok and other Sierra Nevada native American groups. As a regional Indian museum, the collection at Chaw'se includes Northern, Central and Southern Miwok, Maidu, Konkow, Monache, Nisenan, Tubatulabal, Washo, and Foothill Yokuts. Examples of basketry, feather regalia, jewelry, arrow points, and other tools are on display.
Museum Hours: (11 am to 3 pm Monday - Friday) (10 am to 4 pm Saturday - Sunday)
Recreation - A 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. There is also a small picnic area next to the museum. Please do not use the campsites for picnicking.
Camping Information - 23 developed sites with pay showers - 1 group site - 45 environmental sites. Please contact the park directly for detailed camping availability.
Campsites are available on a first-come, first-served basis. The park is open for camping all year, but is subject to closure during times of heavy snowfall. The park has 23 campsites with paved parking (trailers/motor homes to 27-feet); tables, food lockers, fire rings, piped water and restrooms with flush toilets and showers. Wood gathering is not allowed but firewood may be brought in or purchased at the park.
Camping in the U'macha'tam'ma' sites (bark houses to the north) is a unique experience. Here you can "get away from it all" and get back in touch with the natural world while simultaneously learning something about Miwok life.
Seven bark houses, each one suitable for up to six people, have been constructed in a secluded area of the park. They can be reserved for a group of up to 44 people. The camping is primitive; therefore you must haul water, supplies and equipment 200 yards or more from the parking area, but your time here will be unforgettable. Reservations can be made up to six months in advance by mail. Reservations cannot be made by phone. Contact for park for application forms and further information.
