August 1, 1934: "Signal Tree lookout: There is a road to this point. There is a 100 foot treated tower available for this point but no 7 x 7 foot cage for the top. As I understand it from Mr. Mercer, the original plan called for the 100 foot tower and a ground house at this place. However, there is no house available. It seems to me that further investigation should be made at this point and decision made as to whether or not the house when built should not be placed on a 40 to 50 foot treated tower." (To Regional Forester from Forest Supervisor, Umpqua - CCC-)

October 18, 1934: By Mrs. T.G. Lawson: The old Signal Tree is no more. It has stood, for nobody knows how long, on the southwest rim of the Coast Range mountains surrounding Camas Valley. It was only to be expected that it should go. The old and one time useful things must give place to the new and modern, but with the loss of the old tree goes one of the favorite landmarks. The old Signal Tree was for years a favorite place for hikers who enjoyed a real hike with lots of climbing with it and the tree and the old cabin by it have been the scene of many a picnic. In the initials carved into the tree and cabin logs can be read many stories of romance and happiness. For many years the tree was used as a lookout for the fire patrol association. The tree itself was a large red fir. Pipes had been driven at intervals, the ends of the pipe being turned upward, to form a spiral ladder upon which observers could mount to the top of the trunk, where they had an unobstructed view for miles in every direction. The pipes driven into the tree caught rainwater which was drained into the heart of the wood until at last the tree became dangerous and has to be removed. Ed Florence and a crew of CCC men from Camp Bradford have completed a 100-foot lookout tower to replace the old tree and its observation platform, which have been removed. The site, however, will lose none of its popularity for the road, built by CCC crews, now makes it possible to drive to the lookout by automobile and the road has been in constant use during the summer months, especially on Sundays, when sightseers have thronged the spot to enjoy the wonderful view from the mountain top. The outline of this new lookout can be plainly seen from Camas Valley on a clear day." (Roseburg News-Review)

June 19, 1942: "This post was visited on June 6, the observers were Mr. and Mrs. Claude Church. Improvements consist of a 14x16 ground house, with shake siding. It has been sealed in but continues to be draughty. Additional sealing-in with building paper and battens should alleviate the situation. Storm windows, a good combination heating and cooking stove, and an extra 10x10 sleeping room are needed. Good wood trees are handy so the fuel wood situation is excellent. A 101 foot tower with a 7x7 cab is used for fire detection. It is of little use for AWS work except during good weather conditions. A garage and woodshed are needed. The road to the post is in poor condition. Several mud holes near the top need draining. The big trouble with any maintenance is that loggers tear up the road if it is fixed half-way decently. Some cooperative project with the loggers should be worked out by the Association to keep the road passable in winter." (Inspection Report from W.N. Parke, AWS Inspector, to James Frankland, USFS)
