Usually human remains returned to tribes get reburied, with other artifacts it depends, but regardless they don't rightfully belong to the anthropologists or archeologists who took them or dug them up or the university that's been holding on to them, it should not be up to them what happens to the items, it should be the decision of the descendants of the people whose bodies we're talking about or who made the items. Whether they have their own museum or loan them to a museum or bury them or whatever.

The Wiyot tribe this article discusses does have a Historic Preservarion Office and a cultural center.
