In 1932 Adelaide and Fred Smith established the Plumas Pines Resort on the west shore of Lake Almanor, located between the Lake Almanor and the relocated Prattville Cemetery. On July 15, 1932, Adelaide became the postmaster of the newly created Almanor Post Office. The post office was seasonal in nature, only open during the summer, i.e. May 1 to September 30.. It should be noted the Chester Post Office originally was a seasonal post office.
In September 1951, Adelaide Smith informed the postal authorities and the public that she would retire as the Almanor Postmaster effective September 30. It should be noted that her husband Fred had passed away in 1946, but she kept the resort running. In the spring of 1950, she sold the Plumas Pines Resort to V.Y. Briggs.
Of a final footnote, the following year on June 16, 1952, the Canyon Dam Post Office opened with Emmett W. Bishop, serving as first postmaster.
