National parks preserve some of the most unique landscapes in America. Visitors to Badlands National Park in South Dakota are often shocked at the sudden appearance of these colorful formations rising out of the surrounding green plains. The rock formations and amazing fossil beds give us important evidence of the dramatic natural history of the area. Just another reason why national parks are great outdoor classrooms!
