Nebraska Sandhills

The Nebraska Sandhills covers approximately 19,600 square miles, or 50,800 square kilometers, across north-central Nebraska. It is one of the largest stabilized sand dune regions in the Western Hemisphere. The sheer scale of the region makes it a unique geographic feature in North America.

The dunes were formed primarily during the Pleistocene and Holocene epochs, but today they are mostly stabilized. They are now largely vegetated by mixed-grass prairie, which prevents the sand from blowing. However, severe droughts in the past have temporarily reactivated the dunes.

Despite the sandy soil, the region supports extensive cattle ranching and agricultural operations. The deep sand acts as a massive sponge, holding water that feeds the Ogallala Aquifer and creates lush grazing land. It is considered one of the most productive beef cattle regions in the world.

While not a single massive national park, large portions of the region are ecologically managed and protected by groups like The Nature Conservancy. They work to preserve the fragile, unique prairie ecosystem and its native wildlife. The region contains several national wildlife refuges protecting migratory birds.
