Terra Community Alliance Foundation is a Utah 501(c)(3) private foundation. Its public site describes a mission of restoring soil health and reclaiming food sovereignty with Indigenous nations.

Programs named on that site include mineral-rich soil amendments, garden sample kits with instruction by Abigail Cyr, and work with Tribal farmland — including 2026 notes on Lower Brule Sioux Tribe acreage and Wind River producers.

Utah Seabed is a mineral partner supporting related-use donations. Partnership is not a claim of tribal endorsement of Utah Seabed, and guest remarks on the foundation’s educational videos are theirs — not geologist reports on the Antelope bed.
