Below is a timeline of the history of the wild horses in Theodore Roosevelt National Park in Medora, ND. These horses are managed by The National Park Service (NPS), NOT the BLM. However, both agencies are governed by the Department of the Interior. A HUGE thank you goes out to Castle McLaughlin for her research on these horses that ended with her paper being published in 1989. Her paper filled in the majority of the blanks on this timeline.
