LEWIS & CLARK COUNTY
FEDERAL BUILDING (HELENA)
Helena National Forest
July 26, 1933: "A lookout tower has been established on the roof of the federal building equipped with an Osborn fire finder which will enable forest service officials to more quickly determine the location of fires.
The new lookout on the roof of the federal building has been particularly valuable in locating fires north and northeast of Helena, particularly in the Big Belt mountains." (The Independent Record)
