This is a big park. 

This park is in South Dakota. 
It has tall rocks and lots of grass. The land is dry and hard to cross. This is why it has a bad name. 
Long ago, people hunted here. They left tools in the dirt. You can still find them today.
You can also find old bones. These are fossils from long ago. They show what lived here. 
It is a very special place to see.
Badlands National Park is in South Dakota. 

Many people have lived here. Native Americans used the area for hunting for 11,000 years. The Lakota people were the first to call it the "bad lands." The park has two main parts. The North Unit is a wild area. The South Unit is part of the Pine Ridge Indian Reservation. The Oglala Lakota tribe helps manage this part.
Scientists find many fossils here. These are old bones from animals that lived 33 million years ago. The park also helps rare animals. People put black-footed ferrets back into the wild here. You can visit the Ben Reifel Visitor Center to learn more.
Badlands National Park is a special place in southwestern South Dakota. 

Nature works in many ways here. The wind and water shape the land over a long time. This creates the rugged terrain we see today. The park is a home for many living things. One very important animal is the black-footed ferret. It is one of the most endangered mammals in the world. Scientists worked to reintroduce these ferrets into the wild here. The park also manages the nearby Minuteman Missile National Historic Site. 
People have a long history with this land. Native Americans used it for hunting for 11,000 years. The Lakota people were the first to call it the "bad lands." This name comes from the extreme heat and lack of water. The land was very hard to travel through. In 1868, a treaty said the land belonged to the Sioux. However, the United States took the land in 1889. The Sioux held important ceremonies here, like the Ghost Dance, in the 1890s. 
Scientists find amazing things in the ground here. The area is famous for its many fossils. These fossils show what life was like 33 million years ago. In the 1840s, people began to find fossilized bones. By 1854, many different species had been discovered in the White River Badlands. These include mammals from the Oligocene period. Today, the South Dakota School of Mines still studies these fossils. Researchers from all over the world come to learn from this site.
The park has changed many times over the years. It started as a monument on March 4, 1929. It officially became a national park on November 10, 1978. During World War II, the U.S. Air Force used part of the land. They used it as a range for practice bombing and shooting. This part of the park is now managed by the National Park Service with the Oglala Lakota tribe. You can visit the Ben Reifel Visitor Center to learn more.
Badlands National Park is a significant protected area in southwestern South Dakota. 

The rugged landscape was shaped by intense natural forces. Over long periods, water and wind eroded the earth to create steep formations. This process revealed deep draws, high tables, and rolling prairies. The name "Badlands" reflects this difficult environment. The Lakota people named it for the extreme temperatures and lack of water. French-Canadian fur trappers also found it difficult, calling it "les mauvaises terres pour traverser." This translates to "bad lands to travel through." 
Native Americans have utilized this region for 11,000 years. Paleo-Indians and the Arikara people used the area for hunting. Archaeological records show they camped in secluded valleys. They chose places where fresh water and game were available all year. Today, eroding stream banks still reveal their history. You can find charcoal from their campfires and stone arrowheads in the soil. These tools were used to butcher animals like bison and rabbits. 
The history of the land involves complex legal and social struggles. In 1868, the Second Treaty of Fort Laramie promised the land to the Sioux. However, the United States broke this treaty in 1889 and confiscated the territory. This period was marked by the Ghost Dance movement in the 1890s. Followers of the prophet Wovoka performed these ceremonies to revive the souls of the dead. One of the last known Ghost Dances occurred at Stronghold Table. This led to a period of intense conflict between the Sioux and the U.S. military. In 1980, the U.S. Supreme Court awarded compensation for the treaty violation, but the Sioux did not accept the money.
Scientific discovery has made the White River Badlands famous worldwide. The area contains the richest deposits of Oligocene mammals. These fossils provide a window into life from 33 million years ago. Paleontological interest grew in the 1840s when traders found fossilized remains. In 1843, Alexander Culbertson found a jaw fragment. A physician named Hiram A. Prout published a paper about it in 1846. He initially called the creature a Paleotherium. By 1854, scientists had discovered 77 distinct species in this specific region. 
The land also served a military purpose during the 20th century. During World War II, the U.S. Army Air Force used part of the Stronghold District. It functioned as a gunnery range for air-to-air and air-to-ground exercises. This era changed the lives of local families. In the 1940s, 125 families were forcibly relocated from their homes. Some residents even had to hide under tractors to avoid falling bombs. After the war, the South Dakota National Guard used the area for artillery practice. Much of this land was eventually returned to the National Park Service. Some discarded bullet cases and unexploded ordnance remain in the ground.
Badlands National Park has evolved through several administrative stages. It was first authorized as a national monument on March 4, 1929. It was not officially established until January 25, 1939. The park was later redesignated as a national park on November 10, 1978. In the 1950s, the Ben Reifel Visitor Center was built under the Mission 66 plan.
