American Bison at Custer State Park
A mature American bison grazes in the rolling prairie of Custer State Park in South Dakota, part of one of the largest publicly owned herds in the United States. Once on the brink of extinction, the park’s bison herd—established in 1914—now numbers more than a thousand animals, representing a critical effort in the preservation of the species. These massive mammals, capable of weighing over a ton, roam freely across the park’s 71,000 acres of mixed-grass prairie and ponderosa pine forest. The setting reflects both the ecological restoration of the Great Plains and the enduring legacy of America’s native megafauna, which has been tied to the land for millennia.
