Simpson Springs (Tooele) are twenty-five miles west of Vernon. Captain J. H. Simpson was a U.S. military officer sent by the government to explore a western railroad route. Simpson's route was later used for the Pony Express and Overland Stage. He camped at the springs on October 23, 1853, and first named them Pleasant Springs because the water was excellent. The springs were later named to honer Captain J. H. Simpson.
