The Sandhills region is a unique geographical area located in the central part of the United States, primarily in Nebraska. It is characterized by rolling sand dunes, grasslands, and a distinct ecosystem that supports various plant and animal species. The region was formed by ancient windblown sand deposits and is known for its sandy soils, which are often used for agriculture, particularly for growing corn and soybeans. The Sandhills cover approximately 19,600 square miles and are one of the largest grass-stabilized dune regions in the world. This area is also home to several lakes and wetlands, providing habitats for wildlife such as waterfowl and deer. The Sandhills play a crucial role in the local economy, supporting ranching and tourism activities.
