A dugout home, a building based in a hole or depression dug into the ground, near Pie Town, New Mexico, US, in 1940. These structures are one of the most ancient types of human housing known to archaeologists. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof.Photo: Russell Lee; Restoration: Lise Broer
