T Lake Mountain

The tower was of a lighter weight than the 1917 design and had no stairs but only a ladder up the exterior to get to the top.

In 1918 or 1919, wooden steps were added within the structure to ease access to the top of the tower.

The Aermotor company later developed a self-supporting staircase for installation in the towers purchased in 1916.

Due to aerial detection that was developed, the tower was closed at the end of the 1970 fire lookout season.

The tower was deemed as not necessary to fire lookout purposes and also a "non-conforming" structure in the newly established West Canada Lakes Wilderness Area.
