July 12, 1958: "Two men waiting in the woods with a damaged helicopter will have to spend another day there because the parts needed to repair the craft didn't arrive in Missoula Friday in time to be shipped to them. The helicopter was disabled Wednesday in landing at Elkhorn Point lookout in the Selway-Bitterroot primitive area north of the Salmon River breaks in Idaho. The trip to them will be made Saturday with another helicopter carrying blades for the rear rotor and a rotor shaft along with a mechanic. The two men are Stan Greenup, a Bitterroot National Forest Employe, and Fred Gerlach of Missoula, pilot who flew Greenup to the lookout to prepare it for summer use." (Billings Gazette)
