August 11, 1955: "A stricken forest service lookout, stationed at Middle Fork peak in the primitive area, was brought out Friday by helicopter to Salmon for medical attention. Gary Hathaway, Idaho Falls, a forestry student at the University of Idaho, radioed for help early Friday morning and a 'copter and first aid man was assigned to the emergency. Hathaway was taken ill Thursday night and suffered chills and fever and periods of unconsciousness. Piloting the 'copter was Earl Thompson, Seattle, Washington of the Aero Copter firm, which has a contract with the forest service. Leonard Krout, Missoula, Montana, was the first aid man, who remained on the remote lookout while Hathaway was flown to Salmon. The 'copter left Missoula at 7:05 a.m. Friday and landed near the 9,130 ft. peak about two hours later. Thompson was unfamiliar with the country and lookouts along the route radioed his position. The 'copter and his passenger was delayed when it was necessary to put the flying windmill down on McDonald flat because of a broken fan belt. The part was replaced and the 'copter landed at the municipal airport at Salmon about 10:30 a.m. Hathaway's malady was diagnosed by two Salmon physicians as being 'tick fever', the result of a tick which he had removed from his back about five days before, according to a forest service spokesman."
