January 28, 1945: "The Pine district utilized four women as lookouts--one on Trinity mountain, relieved on Sundays by another, and two on House mountain and Danskin lookouts, who relieve their husbands on Sundays. On Trinity was Miss Patricia Anne Heath, of Prairie." (Idaho Statesman)
December 13, 1955: "A ground party was being organized in Boise and it was on its way with snowshoes to retrieve the men. Military aircraft were to provide a constant air cover until the men are brought out of the rugged and snow covered terrain. Hanks reported he was in good condition and Stowell said he had cuts about the face and had lost a few teeth, the Air National Guard reported. The men apparently had spent the night in the Trinity lookout station. Searchers reported seeing a path through the snow from the point of the crash to the lookout." (Idaho State Journal)
1956: An L-4 cab was constructed atop a 10-foot concrete first level.
