History

The Topaz post office opened in 1885, closed in 1922, and re-opened in 1926. The name was transferred from the original site of the village, which developed on the ranch of T.B. Rickey. Mrs. Rickey named it based on the color of the local quaking aspen trees. The post office is now located and has been operated by the Robert William Mckay Family Ranch since the 1920s.
