Pine Grove, CA — Indian Grinding Rock State Historic Park isn´t a well known state park because of its off the beaten path location but it´s a gem nonetheless.
The 135-acre park is located in Pine Grove east of Jackson in Amador County. It holds the largest collection of bedrock mortars in North America – an outcropping of marbleized limestone with 1,185 mortar holes.
The park is also home to the Chaw´se Regional Indian Museum featuring a reconstructed Miwok village and ceremonial roundhouse.
Park staff is seeking volunteers to help with preservation and interpretation. This Saturday´s open house will offer information on the different volunteer opportunities.
It takes place at the park museum form 10 a.m. to 12 p.m.
Further training is scheduled for March 10 and 17, from 10 a.m. to 3 p.m.
