The marble grinding rock is fragile and very susceptible to weathering and chipping. The natural elements are claiming many of the petroglyphs, so please stay off the rock and respect this irreplaceable reminder of indigenous Miwok culture. HISTORY The Miwok The Northern Sierra Miwok, who settled in this area many centuries ago, established their villages alongside the rivers and streams of the Sierra Nevada — from the Cosumnes River on the north to THE GRINDING ROCK AND the Mokelumne River on the south.

This association of rock and instruments, and the brain art and bedrock mortar pits was used to tan hide. is unique in North America. Plant foods were generally Except for one other small collected and processed by Sculpture of Miwok dancer Bark house museum exhibit women while men trapped, fished, and hunted. All resources were portioned so they would continue to be available, and little or nothing was wasted. For example, a plant called soap root was mashed and used not only as soap, but also to stun and catch fish. Its leaves were eaten fresh, and the bulb could be baked and eaten. The dried, fibrous leaves were bundled and used as a brush. Acorns, the mainstay of the Miwok diet, were gathered in autumn, dried, and stored in large granaries (cha’kas) made of poles interwoven with slender brush stems. Resembling large baskets, the cha’kas were thatched with short boughs of white fir or incense cedar to shed snow and rain and then lined with pine needles and wormwood to repel insects and rodents. Acorns are rich in nutrition, but because they contain a lot of tannin, they are bitter to the taste. To make them edible, the Miwok cracked and shelled them, and placed the acorn meat in the mortar holes (chaw’se) in the large flat limestone outcropping in the meadow to be pounded with a stone pestle to the texture of fine Reconstructed Miwok village meal. The Miwok took the meal to the creekside and poured water through the meal to leach out the tannin. The prepared meal was mixed with water in a large, watertight cooking basket. Hot rocks were added to the acorn mush or

Los ciervos eran el recurso animal más importante y todas sus partes se utilizaban. La carne se usaba como alimento; la vestimenta se hacía con el cuero. Los cuernos, huesos y cascos se usaban para construir herramientas e instrumentos y el cerebro se usaba para curtir el cuero. Generalmente, las mujeres recolectaban y procesaban los alimentos vegetales mientras que los hombres atrapaban animales, pescaban y cazaban. Todos los recursos eran racionados para que siguieran estando disponibles y se gastaba muy poco o nada. Por ejemplo, una planta llamada jabonera se aplastaba y se usaba no solo como jabón, sino también para aturdir y atrapar peces. Sus hojas se comían frescas y el bulbo se podía hornear y comer. Las hojas secas y fibrosas se ataban y se usaban como cepillo. Las bellotas, el pilar de la dieta de los Miwok, se recogían en otoño, se secaban y se almacenaban en graneros grandes (cha’kas) hechos de varas entretejidas con tallos delgados. Con un parecido a canastos grandes, los cha’kas se tejían con Aldea Miwok reconstruida ramas cortas de abeto blanco o cedro de incienso para repeler la nieve y el agua de lluvia y luego se forraban con agujas de pino y ajenjo para repeler los insectos y los roedores.
