November 26, 1925: "Tire mountain and Mount June, in the Cascade national forest, probably will be designated as forest fire lookout points, according to Nelson F. McDuff, supervisor of the forest, who, with H.E. Haefner, ranger located at Westfir, ascended these peaks a few days ago. If these mountains are designated as lookout points, they will take the place of two others in the forest and will not be additional points, said the supervisor. Both are higher than some others that have been used for some time past." (Morning Oregonian)
