What kind of habitat did the Navajo live in?

They lived, and some still live, in hogans which are earth houses. It has a wood framework covered with clay forming a dome. There is always a door facing the morning sun. They have a smoke hole in the center. They have four support logs to start the building, one for each direction. They come in "male" and "female" styles. The round ( or hexagonal or octagonal) dome shaped ones that are female are the most common ones today. Most traditional ceremonies must take place in a hogan. Today some hogans are made of modern building materials. Navajo for hogan is "hooghan".

The hogan is described in the creation stories and each part has symbolic meaning. Changing Woman was raised in the first one. The earliest hogan remains have been found in the Dinetah area ( the upper San Juan river basin) and are 1100 years old.

The Navajo (The Spanish interpretation of the Tewa Word for for "farmland in river bottoms" or "wide fields") people are the largest federally recognized tribe of the United States. Even in the earliest years, these hunter/gatherers lived in what is now Arizona and New Mexico and also Utah and Colorado.
