Inscription. Petroglyph Area “Petro” means rock, “Glyph” means writing. Archeologists speculate that pre-historic cultures used petroglyphs to depict aspects of ceremonial significance. These petroglyphs, which are carved in metamorphosed sandstone rock, are estimated to date back to pre-Maidu occupation from 5,000 – 10,000 years ago. In 1972, these petroglyphs and interpretive site were placed on the National Register of Historic Sites at the Smithsonian Institute.

5. Grinding Rocks/Bedrock Mortars

Maidu Indians used grinding rocks as food preparation utensils. Archeologists use the term, “bedrock mortars” to describe these unique tools, which were found standing alone or found among rocks. Indian women used the grinding rock, along with a linear rock called a “pestle”, to grind grass seeds, acorns and other foods during the food preparation process, which included gathering, storing, teaching and cooking. Other utensils such as baskets, stones, brushes and stirring sticks were also used in cooking. Food preparation, as with most aspects [...] was considered a sacred job.
