About an inch a year wears off the buttes of Badlands National Park, 75 miles east of Rapid City, South Dakota. The park estimates they have another 500,000 to a million years left. In the mid-1800s, 77 of the 84 fossil animal species then known in North America came out of these beds, and paleontologists still prepare fossils in a lab in the park, answering questions while they work. Off-trail hiking is allowed, and the park warns that the formations are easier to climb up than down. The Notch Trail, 1.5 miles round trip, climbs a log ladder and runs along a ledge to a view of the White River Valley; skip it in or after heavy rain, when it turns treacherous.
