Amador - Indian Grinding Rock SP Indian Grinding Rock State Historic Park is a 135 acre park that preserves a large outcropping of marbleized limestone, where local Indians havested acorns. This resutled in the development of over 1,185 mortar holes, the largest collection of bedrock mortar holes in North America.

There are a number of petroglyphs, some of these are thought to be as much as three thousand years old. There are also a number of trails that lead you through the meadows and surrounding forest. There is a Miwok village, complete with a roundhouse, bark houses, and acorn granaries, that were reconstructed.

The Chaw'se Regional Indian Museum has been designed to reflect the architecture of the traditional roundhouse. Exhibited in this museum are outstanding examples of the technology and crafts for the Miwok and other Sierra Nevada Native American groups.

The Park has 23 campsites accommodating trailers and motor homes to 27 feet.

Location:
Take State Highway 88 East through Jackson to the town of Pine Grove. Turn left on the Pine-Grove-Volcano Road and drive about a mile and a half to the park.
