Theodore Roosevelt National Park is on Interstate 94, at Medora, North Dakota. A north unit is 90 kilometers (56 miles) north on US. 85. TR’s Maltese Cross Cabin is in the south unit, but the park celebrates more than the 26th President’s energetic protection of public lands. Magnificently colored and worn badlands lie on both sides of the Little Missouri River interspersed with grassy ranges where adventurous men, Roosevelt among them, enterprised in the open-range cattle business. Populations of bighorn sheep, bison, and antelope, among the large game animals once hunted to extinction, have been restored. The visiting season is May through October. The park has campgrounds in both north and south units. Mailing address: Medora, North Dakota 58645.
