"The Navajos have long raised sheep to provide them with wool to weave blankets and for meat. Despite a forced stock reduction in the 1930s that caused a great deal of controversy, the Navajos maintain their identity as sheep ranchers into the present day." (NAU Cline Library) Caption at link
The Navajo tribe in New Mexico and Arizona built hogans. Hogans have six sides built from wood poles and adobe (mud). There was one room in the hogan and the doorway faced to the east. Beautiful Navajo rugs covered the doorway. There was a hole in the roof so smoke from the fires could escape.
