Indian Grinding Rock State Historic Park
About the park
Indian Grinding Rock State Historic Park is in the Sierra Nevada foothills 11 miles east of Jackson, CA. The park is nestled in a little valley about 2,400 feet above sea level with open meadows and three species of oaks that produce acorns. The Northern Sierra Miwok settled in this area many centuries ago and gathered acorns as a main staple of their diet.
The 135-acre park preserves a great outcropping of marbleized limestone with some 1,185 mortar holes -- the largest collection of bedrock mortars in North America. A ceremonial roundhouse and reconstructed bark houses are present in the center of the park. Additionally, camping is available on the southside of the park.
The park is northeast of Stockton in the lower foothills of the Sierra Nevada mountains. Take State Highway 88 East through Jackson to the town of Pine Grove. Turn left turn on Pine Grove-Volcano Road and proceed approximately 1.5 miles. The first left is the campground and the second left is the park’s main entrance to the parking and the museum.
