Olive is ten miles north of Broadus on the Mizpah River in the southeastern corner of the state. The Mizpah is a fork of the Powder River and its Biblical interpretation means "lookout" or "watch tower." The river was named by Captain Williams Raynolds, who was surveying the northwest for possible US Army wagon routes.
Olive is located near the county seat, Broadus, which is home to the Powder River Historical Museum. The museum contains many valuable historical collections, including photos and books, Indian artifacts, old guns and ammunition, pre-1900 buggies, vintage autos, rebuilt engines, threshing machines, tractors and farm implements.
