More About Us



The Mutsun-Ohlone people have maintained and been responsible for this land since time immemorial.


Federally Recognized “Indian Country”

In 1911, United states President William Taft officially recognized Sebastian Garcia and the Chualar Tribe when he signed the Trust Patent granting him and his Tribe and allotment of land , which is now part of Indian Canyon today .


Continuous Legacy of Land Stewardship

Upon Sebastian Garcia’s death in 1933, The Department of the Interior declared his grand-daughter, Elena Sanchez, to be the legal heir of his allotment, thereby designated her as the new Tribal Leader of the small band of the Chualar Tribe in Indian Canyon.


Ann-Marie reclaims ancestral homelands

Upon Elena Sanchez’ death in 1974, her daughter, Ann-Marie Sayers was designated the new Tribal Chairperson of the Costanoan Tribe in Indian Canyon. Ann-Marie updated the Tribe’s name from the Chualar Tribe to the Costanoan Tribe to honor and recognize the region in which Indian Canyon was located.


Opening the land for all Indigenous peoples

Indian Canyon is available to all indigenous people to use for performing traditional ceremonies — something that was prohibited until the 1978 passage of the American Indian Religious Freedom Act. In welcoming other indigenous people to Indian Canyon, Sayers continues the land’s long history as a refuge.


Honor Truth in History

Indian Canyon has in excess of 5,000 visitors annually from a caring host of many indigenous ceremonies and gatherings, fundraisers, school field trips. Indian Canyon is NOT a park, and we are only open to the public BY APPOINTMENT ONLY.
