What type of home did the Navajo live in?

Many Navajo, or Dine', still live in the traditional hogan. It is a 6 or 8 sided building made by stacking logs similarly to a log cabin. When finished it appears to be round. The roof is made of smaller diameter wood that is covered with brush to fill the holes and earth over. The smoke hole is centered on the roof. The door faces east to greet the new day's sun. There are no Windows.
