Most of the floors are restored with adobe mud and sealed with boiled linseed oil (traditionally, a mix of mud, ox blood and wood ash was used to make hard, non-dusting floors). The roofs are supported by large vigas (beams) that are in turn covered with either rajas (split cedar boards) or latillas (aspen poles). On top of the sticks, layers of grasses, cattails, or chamiso (sage) were placed and 24 inches or more of earth piled on top as the final covering from the elements. The shuttered window openings, which would have been considerably smaller than the current ones (based on more recent scholarship), would have been totally open or covered by oiled rawhide or the occasional sheet of mica.
