The Eatonville Post Office will be dedicated in her honor at a ceremony on Friday, Sept. 5. Congressman Dave Reichert sponsored legislation to authorize the dedication, which will be marked with a plaque.
Anderson's father, Reichert and Park Superintendent Randy King are scheduled to speak at the event.
Anderson had served with the National Park Service for 12 years. She was killed while attempting to stop a man fleeing from the Longmire Ranger Station after she set up a traffic block.
Four others were injured in the shooting. She is survived by her husband, who is also a park ranger, and two young children.
