Shelter:

The Navajo Tribe had two types of houses. The first type of house was called a hogan. The hogan was a one-room house and it was made out of shells, logs, mud, and turquoiise. This type of house was good for desert living and the mud walls kept the room cool in the summer and warm in the winter. It had one door which had to face East towards the rising Sun. The second type of house was an adobe house. The adobe house was made from mud, straw, and sticks. They mixed together the materials and formed them into bricks. Then they would lay them in the Sun to dry. Sometimes they built entire villages from adobe houses and they would also stack adobe house on top of each other like apartment buildings.
