Located west of the popular Lake George tourist area, Hadley Mountain Fire Tower was one of the original ten steel fire towers purchased by the state. The 40’ Aermotor LL-25 structure with 7’ x 7’ metal cab was placed in the middle of a 12,000-acre area that had burned repeatedly during the previous decade.

From The Aermotor Model LL-25 by Bill Starr, NHLR State Registrar: "The AerMotor Model # LL-25 was proposed to the State, and ten of these towers were ordered. All were delivered by rail road early in 1916 and nine were immediately erected at Cathead, Fort Noble, Hamilton, Makomis, Moosehead, T - Lake, Tommy, Wakely, and Woodhull Mountains. The last tower was for Ohmer Mountain although the State was unable to secure an agreement with the land owner there, so Hadley Mountain was selected to replace Ohmer. Construction of the tenth tower began late in 1916 on Hadley and was not completed until early in 1917."
