December 12, 1940: "Huge timber wolves with tracks as large as those of a cow were reported in the vicinity of Signal Peak last week by two Indian youths stationed at the lookout there. One of the lookouts, Martin Oritz, a June graduate from Witchita, Kansas high school, saw a timber wolf prowling within 300 feet of the station. The two Indian youths, Blair Weeks, and Oritz, will remain at the Signal Peak station until March completely isolated from the outside world except for telephone and radio. The lookouts report twice daily by short wave radio to the Satus pass station. Their reports are on the air between 8:00 and 8:10 a.m. and between 6:30 and 6:40 p.m. Their call letter is KPGI."
