Sulphurdale is a ghost town in Beaver County, Utah, United States. Sulphurdale was established in 1870, but mining did not begin in large scale until 1883. Homes, a school, a store and company offices were built in town. Despite the heavy mining activity, high quality sulfur was difficult to find. Production slowed in the 1940s and 1950s, and in 1966, the mine and mill shut down. By the end of the 1970s, Sulphurdale was abandoned.
