Death Valley Days was a radio Western in the United States. It was broadcast on the Blue Network/ABC, CBS, and NBC from September 30, 1930, to September 14, 1951. It "was one of radio's earliest and longest lasting programs." Beginning August 10, 1944, the program was called Death Valley Sheriff, and on June 29, 1945, it became simply The Sheriff.
As an anthology series, Death Valley Days had no continuing cast of characters other than The Old Ranger, who introduced and narrated each episode. Over the years, The Old Ranger was played by Jack MacBryde [photo], Tim Daniel Frawley, George Rand, and Harry Humphreys. In the later versions (Death Valley Sheriff and The Sheriff) Sheriff Mark Chase was portrayed by Robert Haag, Donald Briggs, and Bob Warren. Announcers were George Hicks, Dresser Dahlstead, and John Reed King.
