Badlands National Park
Badlands National Park  is a United States National Park that is located in southwestern South Dakota. This park is marked by rugged terrain and formations that resemble a science fiction landscape of another world. These rock formations take on the shapes of domes, twisted canyons and slanted walls, often striped in different colors. The formations contrast sharply with the rolling hills and prairies in which they stand.
In addition to the rock formations, the park contains the largest, protected mixed grass prairie in the United States. The most endangered land mammal in North America, the black footed ferret, was re-introduced to the 64,000-acres Badlands Wilderness Area. The park also contains the world's richest fossil beds from the Oligocene epoch, dating back around 20-35 million years.
