July 29, 1914: "In order to make the immediate detection of forest fires in the south end of the county more easy, Forest Rangers Walter Allison and Bun Moore are now constructing a tower on Lookout Mountain, the highest peak in the range, and from this they will scan the forests for many miles with a strong glass. The tower is now almost completed and one man will be stationed there most of the time. Prompt measures are necessary to check a forest fire and early discovery is a great aid to the rangers. The telephone lines are a great help but the glass in the tower will be much superior. So far this season, there have been no fires in the south end, the constant vigil of the rangers and the many warning signs tacked up by them acting as a prevention. The grass and underbrush in the mountains is pretty dry now and constitutes a menace. Lookout Mountain is about fifteen miles south of Lehman Springs and has an elevation of about 6000 feet." (East Oregonian)
August 2, 1914: "Forest rangers on the Umatilla forest are engaged in erecting a 65-foot 'fire tower' on the top of Lookout Mountain, one of the highest peaks in the forest. Owing to the fact that only the raw material to be found in the forest was available for building the tower, its construction was a difficult task. It is nearing completion, however, and will be equipped with a powerful glass and 'fire finder.' A man will be on duty constantly and with the aid of the equipment at his command will be able to locate every fire within a radius of 75 miles, almost as soon as it is started." (The Morning Oregonian)
September 27, 1921: "C.H. Bowles, Lookout at Lookout mountain in the Ukiah district, terminated his service last week and left by way of Lehman Springs for his home at Dallas. Mr. Bowles reported a total of fifty-nine fires during the season." (Heppner Herald)

September 16, 1947: "Two new lookout towers will be constructed and one lookout house installed. This work may be started as soon as the lookouts are through for the summer months. Towers are to be constructed at Spout Springs and Lookout Mountain and the lookout house at Table Rock. The towers are of frame construction, 83 feet high and with a 14x14 house on top. The new structures will replace facilities that have been in use for many years. The tower at Lookout will go as soon as the firemen leave the station for the fall." (Walla Walla Union-Bulletin)
1948: A 82-foot treated timber tower with an L-4 cab was erected.
2001: The lookout had been staffed for five days when a Forest Service inspection determined the structure was unsafe, the lookout person was moved to the tower on High Ridge. The damage was caused by a strong wind storm in May, consisting of a blown off shutter and a cross support bar that requires replacement.
2004: The cab was lowered by crane from atop the 90-foot tower to make remodeling easier. A new roof, widened catwalk, new handrail and a new door were part of the remodel. The tower has some new crossbraces installed, new stair treads and a new lightning protection system installed.
