What happened
Indian Canyon is land south of Hollister, California, in the Gavilan range. A 2010 Santa Clara University magazine profile says Ann-Marie Sayers built her cabin on her great-grandfather's home site after years of battling the federal government for the land, which she claimed through the Indian Allotment Act of 1887. The same profile says that, as far as the federal government is concerned, Sayers and most Bay Area Native Americans who call the region home are not members of a recognized tribe.
The San Francisco Foundation's profile of Sayers says Indian Canyon consists of about 1,000 acres and is "the only federally recognized Indian territory from Sonoma to the coast of Santa Barbara." Other sources describe the acreage differently, so treat the size as uncertain. The profile also says the land is available to all indigenous people for traditional ceremonies.
The nonprofit based on the land is Costanoan Indian Research, Inc. (CIR). The Indian Canyon community site says it is a registered 501(c)(3) Native American nonprofit with federal ID 68-0287736, at Indian Canyon in Hollister. ProPublica lists Costanoan Indian Research Inc in Hollister under that EIN. CIR's site describes an annual storytelling gathering and a mission to preserve Mutsun Ohlone and California Indigenous knowledge and culture.
The community's site is indiancanyonlife.org; the similar indiancanyon.org is unrelated.
Good to know. Sources disagree on the size of Indian Canyon, from about 1,000 acres to roughly 270. The family is not part of a federally recognized tribe, though the land is described as federally recognized Indian territory.

Research notes. The record names "Indian Canyon Mutsun Band of Costanoan" and could not match an EIN; the nonprofit found here is Costanoan Indian Research, Inc. (EIN 68-0287736), and the tribal-band name was not confirmed. Acreage and the land-history dates differ across sources (about 1,000 acres per the SF Foundation; roughly 270 acres in a 2003 local article that was not opened). The tribe is not federally recognized per the 2010 profile, while the land is described as federally recognized Indian territory. Donations: CIR's page says to make checks payable to Costanoan Indian Research, Inc.
