The Sioux Indians lived in the central plains of North America, including parts of modern-day Wisconsin, Iowa, Minnesota, and South Dakota. Their habitat consisted of prairies, woods, and open plains, with a humid, warm climate in the summer and dry, cold winters. They followed seasonal patterns of growing crops in the summer and hunting buffalo and other game to preserve meat for the winter. The Sioux lived in tipis made of poles and animal skins, wore clothing made from decorated animal hides and fur, and followed cultural traditions like the Ghost Dance ceremony.
