David Harrelson, department manager and tribal historic preservation officer for the Confederated Tribes of Grand Ronde, participates in the Lamprey Creek Awakening, a ceremony to celebrate the naming of Lamprey Creek on Saturday, May 21, 2016 in Corvallis, Ore. The 3-mile-long tributary of Oak Creek had no official name until last August, when it was christened Lamprey Creek by the U.S. Board of Geographic Names at the request of a group of local residents.
