The Badlands were located in southwestern South Dakota. I don't know much about the scientific things, get more details from the official website: http://www.nps.gov/badl/index.htm :p
The beauty of the Badlands is so amazing and how great it formed from very long time ago. These striking geologic contain one of the world;s richest fossil beds. Also it include of the wilderness likes prairie dogs, buffalo... This area is open for backpacking and picnic.
Here's some picture (I believe pictures say thousand words)
Sunset
I spend around 5 hours at Badlands in the morning and go another time for the sunset because the pass is valid for a week. Here's a nice place for the sunset though! Stop at many viewpoint because it looks so different from different angel. There's a trail for you to hike and get closer to the land. I really enjoy this place!
