These parks support unique natural resources, including large areas of northern mixed-grass prairie communities, critical river and riparian habitats, large herds of bison, and two of the four longest caves in the world.
Parks range in size from 444 acres at Fort Union Trading Post National Historic Site, to 242,756 acres at Badlands National Park, and include one national memorial, one national scenic river, one national recreational river, three national historic sites, four national monuments, and three national parks.
