The Ohlone people built massive shellmounds that served as both sacred burials and landmarks.

In short: Before Spanish colonization, the Ohlone thrived along the Northern California coast in a complex network of fifty distinct nations. Today, descendants are reclaiming their heritage by protecting these ancient shellmounds—vast, man-made accumulations of shells and artifacts—that once defined the landscape and served as vital markers for coastal navigation.

The Ohlone inhabited a vast territory stretching from the San Francisco Peninsula to Big Sur, living in approximately 50 distinct landholding groups. Rather than a single unified nation, they were a diverse association of tribes, each with its own traditions, though they shared common practices like the Kuksu religion and a hunter-gatherer lifestyle. They managed their environment through controlled burning to improve seed yields and built dome-shaped houses from tule mats or redwood bark.

Central to their legacy are the shellmounds, or middens, which dot the San Francisco Bay area. These sites, some reaching 60 feet in height, were not merely refuse piles but significant cultural statements. Archaeologists have found evidence of ritualized burials within these mounds, including the remains of animals like wolves and grizzly bears adorned with beads and fiber cordage. These burials suggest a complex cosmology where animals may have served as spirit allies or sacred deity figures.

The arrival of Spanish missionaries in 1769 initiated a period of catastrophic decline, with the population dropping significantly due to forced assimilation and disease. Today, the Ohlone are not federally recognized, yet they remain active in preserving their history. Organizations like the Sogorea Te Land Trust are working to return ancestral lands to indigenous stewardship, while others, such as the Muwekma Ohlone, participate directly in archaeological excavations to reconstruct their past and assert their ongoing presence in the region.
