Why this site

Elkhorn is the quietest unit of Theodore Roosevelt National Park. It's also the unit where the TR-conservation story has to be told most carefully — because the same conditions that made it feel empty to TR were the result of violence, not absence.

The dual story

Two chapters, same ground.

Conservation chapter / Today

The TR / conservation chapter

Theodore Roosevelt bought the Elkhorn property in 1884, the year his first wife and mother died on the same day in New York. The ranch sat on the Little Missouri's east bank, in a stand of cottonwoods about 35 river miles north of Medora. The Elkhorn years (1884–1886) are the period TR's biographers cite as the formation of his conservation ethos. The foundation stones of the ranch buildings are still visible in the cottonwood bottom. They are not large.

Elkhorn is geographically the least-developed of TRNP's three units — no road, no campground, walk-in only. The Badlands Conservation Alliance has campaigned since the early 2000s to protect the Elkhorn viewshed from oil and gas development on adjacent state and federal land. The site was added to the National Register in 2012. BCA's viewshed campaign is the single longest-running conservation fight on the Little Missouri.

Indigenous chapter / Before and after TR

The Indigenous / 1864 chapter

Before TR bought the ranch, the corridor here was Mandan, Hidatsa, and Lakota country. The 1837 smallpox epidemic — brought up the Missouri on an American Fur Company steamboat — killed an estimated 90% of the Mandan population. Mandan villages along the Missouri were abandoned or consolidated. The Hidatsa moved upstream and eventually combined with the surviving Mandan and the Arikara at Like-a-Fishhook Village. Smallpox emptied the country a generation before TR arrived to write about its emptiness.

The corridor's Indigenous story doesn't end in 1837 or 1864. The Mandan, Hidatsa, and Arikara are still here, organized as the MHA Nation. A site profile that closes the Indigenous chapter at the 19th century is doing the same flattening TR did.
