1940: A 40-foot sawn timber tower with an L-4 cab was constructed.
January 22, 1942: "The lookout on Mount Baber which has been closed because the telephone line was down because of the ice storm of several weeks ago will again be opened and observers will be there 24 hours a day." (Corvallis Gazette-Times)
June 24, 1942: "This post was visited June 10. A young college couple, Mr. and Mrs. Keith Bannister, took over this post on May 26. Improvements consist of a 14x14 Aladdin cabin on a 40 foot tower. There is no garage or woodshed. A 16x18 garage and a woodshed should be constructed as soon as possible. The garage should be sealed in, floored and ample windows installed for occupancy as living quarters for the winter. In the summer it can be used as sleeping quarters for the observer off duty. The road to the post was impassable during my visit due to recent heavy rains. An emergency fire crew camp was being fixed for occupancy at the highway terminus of this road and is expected to be in this vicinity all summer. The crew will be used to some extent to improve the road so it can be used next winter in servicing the post. The road leading to the post was badly rutted on the slope near the top. About 3/4 mile of road, from top on down, needs grading and drainage. Graveling would help but it was considered too expensive to gravel with AWS funds, and therefore disapproved." (Inspection Report from W.N. Parke, AWS Inspector, to James Frankland, USFS)
July 22, 1941: "Chester Sparks is the fire patrolman stationed at the Mount Baber lookout this year. He went to work there last week. There has not been a fire here as yet." (Corvallis Gazette-Times)
1969: The lookout was dismantled. The lookout had not been used for several years and between wind damage and vandalism repairs were too expensive.
