Indian Grinding Rock
Indian women used grinding rocks such as these, along with a linear rock called a “pestle”, to grind grass seeds, acorns and other foods during the meal preparation process, which included gathering, storing, leaching and cooking. It is believed each hole here served as many as 3 people, and the six holes here represent the possibility that this encampment contained 18 people total. Acorns, grass seeds, and roots provided a diet rich in starch and fat. These Indians were nicknamed the “Digger Indians” by the local immigrants.
