Earth lodges are old types of houses used by people long ago. They were made out of wood, mud, and animal skins, and they were shaped like a big dome or circle. Inside the earth lodge there was usually a fire in the middle and they had a smoke hole in the top so the smoke could escape. Some tribes used earth lodges for their whole village! People sat around the fire, talked, and had fun with one another. They also used the fire to cook their food. Today, some people still build earth lodges for fun, to remember the old ways of living.
