Often NNAD Navajo archaeologists have traditional Navajo protection prayers or ceremonies done in order to avoid any ill effects to oneself and one's extended family, which might occur as a result of being an archaeologist and handling objects that belong to someone now deceased or walking over a deceased person's house, whether one hundred or thousands of years old.
Although most of the work that NNAD does consists of archaeological survey work, which records and avoids "sites," rather than excavation or digging, the Navajo public usually does not know this until we tell them.
Also, since Navajo Nation Council members are elected every four years, re-education of the newly elected Navajo leaders, including the Navajo Nation president, must be done on a continual basis if NNAD desires continued community and tribal governmental support.
The point being if we were such a great program, then more Navajo students should be in top positions within the Navajo Nation Archaeology Department (NNAD) and the Navajo Nation Historic Preservation Department (NNHPD) by now.
