Before Jon Eagle Sr. began working for the Standing Rock Sioux Tribe, he was an equine therapist for over 36 years, linking horses with and providing support to children, families, and communities both on his ranch and on the road. The work reinforced his familiarity with the land, and allowed him to explore the rolling hills, plains, and buttes of the sixth-largest reservation in the United States. But when he became Standing Rock’s tribal historic preservation officer, he learned that the land still held surprises, the biggest one being that much of that land didn’t belong to the tribe. Standing Rock straddles North and South Dakota, and both states own thousands of acres within the tribe’s reservation boundaries.
“They don’t talk to us at all about it,” Eagle said. “I wasn’t even aware that there were lands like that here.”
On the North Dakota side, nearly 23,500 acres of Standing Rock are managed by the state, along with another 70,000 of subsurface acres, a land classification that refers to underground resources, including oil and gas. The combined 93,500 acres, known as trust lands, are held and managed by the state and produce revenue for its public schools and the Bank of North Dakota. The amount of reservation land South Dakota controls is unknown; the state does not make public its trust land data and did not supply it after a public records request.
And Standing Rock isn’t alone.
Data analyzed by Grist and High Country News reveals that a combined 1.6 million surface and subsurface acres of state trust lands lie within the borders of 83 federal Indian reservations in 10 states.
