A farming community southeast of Puyallup. Orson M. Annis had a farm on which a grove of alder trees grew. It was near Alderton that the Naches Pass trail turned eastward to climb Elhi Hill before continuing up the White River Valley. The post office was established at Alderton on April 12, 1878 and was closed on October 9, 1964. Orson M. Annis was born in Ellery, New York, on August 2, 1828. He came to the Puget Sound country early in 1869 and settled at Alderton. He died August 21, 1900 having lived there for over thirty years. Like other locations in the valley former farmland is being turned into residential neighborhoods.
