Plains Indians lived in tepees, cone-shaped tents covered by buffalo hides. They were typically around 12 feet high, but after the Plains Indians acquired horses, they began to build their homes twice as high.
Because the Plains Indians moved their homes often, they needed homes that were easy to assemble and break down quickly. The tepees also kept the Plains Indians warm in the winter and cool in the summer. The Plains Indians kept their tepee supplies with them instead of finding new supplies each time they moved because the plains often lacked the trees needed to make the long poles.
