Warner Hot Spring California Acorn Cache Real Photo Postcard

Acorn caches, like the one depicted, were vital storage structures used by numerous Native American tribes, particularly in California, where acorns served as a primary food source. These raised platforms with woven granaries protected vast quantities of processed acorns from rodents, insects, and moisture, ensuring food security throughout the year and enabling communities to sustain themselves through leaner seasons. This ingenious method of food preservation was central to the traditional economies and lifeways of indigenous peoples.
