Rainbow, Oregon
Rainbow Oregon

The name of this post office was suggested by Mrs. L. Quimby, whose husband bought the property where the office is situated in May 1922. The office was established July 1,1924, and closed August 31, 1937, with mail to Bule River. Mrs. Quimby selected the name because McKenize River nearby is the home of the popular rainbow trout, Salmo gairdneri.
