These Colorful, Dramatic Cliffs Are a Half Million Years Old

Location: South Dakota
Established: November 10, 1978
Size: 244,300 acres

They call it The Wall. It extends for a hundred miles through the dry plains of South Dakota—a huge natural barrier ridging the landscape, sculptured into fantastic pinnacles and tortuous gullies by the forces of water. Those who pass through the upper prairie a few miles north might not even know it exists. Those who traverse the lower prairie to the south, however, can't miss it; it rises above them like a city skyline in ruins, petrified.

The Badlands Wall, much of which is preserved within the boundaries of Badlands National Park, may not conform to everyone's idea of beauty, but nobody can deny its theatricality. It's been compared to an enormous stage set—colorful, dramatic, and not quite real. Water, the main player on this stage, has been carving away at the cliffs for the past half million years or so, and it carves away an entire inch (three centimeters) or more in some places each year. But there have been other players, too. Beasts with names like titanothere and archaeotherium once roamed here; their fossilized bones can be found by the hundreds. And today the Badlands Wall serves as a backdrop for bison, pronghorn, and bighorn sheep, as well as the million human visitors who pass through the park every year.

A national monument since 1939, Badlands acquired the South (Stronghold) Unit in 1976, adding yet another dimension to the drama. This large stretch of land belongs to the Oglala, and one of their most sacred places is now preserved within it. It was here, on Stronghold Table, that the final Ghost Dance took place in 1890, just a few weeks before more than 150 Lakota were massacred at Wounded Knee, 25 miles south.

Badlands National Park is considered home to one of the world's richest deposits of mammal fossil beds.

The Oglala Lakota Nation, the second-largest American Indian Reservation in the United States, co-manages half of Badlands National Park.

The Badlands average one inch of erosion per year.

Dazzling Time-Lapse Reveals America's Great Spaces October 23, 2013—After quitting a comfortable day job, photographer Shane Black spent two months on the road shooting time-lapses of some of America's most beautiful spots. His "Adventure Is Calling" video is the mesmerizing result, made from about 10,000 of the photos he took.
