1907: "The station on Rocky Mountain was built by the land owners in 1907, before the Fire District was created." (1910 Forest Commissioner's Report)
1914: "Rocky Mountain station was built by the landowners in the summer of 1907. It was built of logs and is not high enough for the territory. A new steel tower, thirty-six foot high, possibly a forty foot tower would be better, should be erected early in 1915. There are two bluffs and I think the tower should be erected on the one most northerly. This tower should be hauled to the mountain during the winter, to save expense." (1914 Forest Commissioners Report)
November 1, 1916: Charles Thibodeau in a report to the State Forestry Commissioner: "I think that it would be advisable to build a new look-out station at Rocky Mountain as the one there is unfit, and I think that a steel tower between 30 and 40 feet high would be what is needed there." (Daily Kennebec Journal)
1917: "Hosea B. Buck, Bangor, Chief Warden, Northwestern part of Aroostook County: We built a good wooden tower 20 feet high, on the south bluff of Rocky Mountain, Twp. 18, R.12. Observations are taken from two points about 1/8 of a mile apart on this mountain. There is a wooden tower ten feet high on the north bluff of the mountain that was in very good condition, so I did not think it best to go to the expense of building a new one this year." (Forest Protection and Conservation in Maine)
1919: "On Rocky Mountain in Twp. No. 18 R. 12, Aroostook County. This station was originally built in 1907, at the expense of those owning land in that immediate vicinity. In 1917 a new log tower was built on another bluff of this mountain. From the two bluffs a view can be obtained in all directions." (Forest Protection and Conservation in Maine, 1919)
1920: Inventory shows a 48-foot steel tower.
June 7, 1921: "Samuel E. Andrews of Bingham, foreman of the Forestry Districts construction crew, was at the department on Monday arranging to take his crew to Rocky Mountain in the northwest corner of the State, where a 48-foot steel lookout tower will be erected. He has just finished a steel tower on White Cap mountain in Piscataquis county." (Daily Kennebec Journal)
October 30, 2017: The lookout structure yielded to the wind, as the cab of the fire tower came down. (Fiddlehead Focus. Com)
