They were both owned and operated by the same Creole families for almost 200 years. This includes not just the landowner owners. Many of the enslaved workers transitioned from slavery to sharecropping after the Civil War.

Theodore Roosevelt National Park, North Dakota

Theodore Roosevelt National Park holds a special place in my heart. It is more than just named for renown conservations and US President Theodore Roosevelt. Roosevelt came to the area as a young man to heal after the death of his wife and mother. It was his experiences here as a hunter and ranchers that inspired his conservation policies as president.

Theodore Roosevelt National Park is a fragmented National Park. The park is made of three different units in Western North Dakota. The two main units – North and South. Visitors to these units have access to scenic drives, over 100 miles of hiking trails and the opportunity to view prairie dogs, bison, feral horses, and many other animals.

The third unit is called Elkhorn Ranch. It is an hour and a half drive along gravel roads from both the north or the south unit. This unit is the site of Roosevelt’s original ranch. It was here that the Maltese Cross Cabin was built and where Teddy lived and worked cattle. The Cabin has been moved to the south unit but visitors are still welcome to explore Elkhorn. There is a 0.75-mile trail to walk with scenic views along the Little Missouri River.

Best Time to Visit: May to September
