Oregon Revised Statutes Property Rights and Transactions § 97.750

(1) Any proposed excavation by a professional archaeologist of a native Indian cairn or burial shall be initiated only after prior written notification to the State Historic Preservation Officer and the state police, as defined in ORS 358.905, and with the prior written consent of the appropriate Indian tribe in the vicinity of the intended action. Failure of a tribe to respond to a request for permission within 30 days of its mailing shall be deemed consent. All associated material objects, funerary objects and human remains removed during such an excavation shall be reinterred at the archaeologist's expense under the supervision of the Indian tribe.

(2) In order to determine the appropriate Indian tribe under this section and ORS 97.745, a professional archaeologist or other person shall consult with the Commission on Indian Services which shall designate the appropriate tribe.
