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.”
