April 27, 1923: "The Rainier National Forest announced the recommendation of the allocation of $1000 for the construction of a lookout house." (The Chehalis Bee-Nugget)
October 1931: "The following brief item appeared in the Oregonian on October 11 under a Chehalis date line: 'According to telephone messages received here Herman Senter of Riffe, a forest ranger working in the Little Rockies in eastern Lewis County, was shot Saturday. He died while being brought out of the mountains.'
From incomplete information received up to the time of going to press, it seems that Herman Senter was the lookout on the Little Rockies in the Mineral District. The fatal accident occurred, it seems, when his revolver became stuck as he tried hurriedly to draw it from its holster, slipped to the ground, was discharged and shot him through the neck. Senter was a very bright, local young man, who it is understood, had given good service at the lookout. Ranger Hampton, on whose district the accident occurred and who was in attendance at the ranger training camp, left for once for Mineral." (Six Twenty-Six)
October 12, 1931: "Thurman Senter, 29, employe of the federal forest service, was the victim of an accident near Morton Saturday evening, in which he was shot through the neck by a bullet from his own gun. Senter, with Don Peters and Clarence Workman, government ranger, were building some cabins about four miles from Little Rocky lookout station. As they completed their work for the day, around six o'clock, Senter went down to a nearby spring to get some water. When he bent over, a gun in his shoulder holster slipped out, struck a rock in the creek and sent a bullet through his neck. Workman stayed with Senter while Peters started out for help. He walked to the Jack Morris place, four miles outside of Morton and there a car was obtained to go to Morton to notify Dr. C.B. Ritchie. The doctor started right out, but did not reach the camp until 3 a.m. Sunday, due to the trail that can be negotiated only on foot or horseback. Senter had died about eight o'clock Saturday night."

February 4, 1941: "A searching plane returning here today said the wreckage of the missing McChord Field twin-motored bomber was 'scattered over about two acres' of timber near the Little Rocky Fire Lookout Station. six miles north of Morton. Palmer Dunlap, Chehalis flier, said he and a companion, using binoculars, first sighted one wing of the wrecked plane upright in the timber. They flew down to within 600 feet of the mountainside and saw additional parts of the plane scattered in the woods." (The Greeley Daily Tribune - Colorado)
