September 1923: "A tower was completed by the first of July." (Six Twenty-Six)
August 1927:"Packer Smith had just returned to Marble Mountain Lookout with the pack string loaded with lumber for the tower, as it was pouring down rain all hands, including Hougland, Foote and Vincent, proceeded to help take the packs off. As most of the horses were about half unpacked, there came two terrific blasts of thunder, which caused a general stampede. The only one that kept his post was Foote and the reason for that was that a horse had stepped on his foot and he was unable to move! One bolt of lightning struck a tree about 200 yards from the tower. L.L. Hougland" (Six Twenty-Six)
February 1928: "Mr. Hougland built a glass enclosed cab on the lookout tower, working into the months of October and November, braving the extremely bad weather in order to finish the job." (Six Twenty-Six)
July 1933: "On June 23, Clarence Stovik, Lookout on Marble Mountain sighted a smoke on Big Goosmus Creek. He immediately notified Assistant Ranger Hugh Cheyney at Curlew, who departed for the fire, after ordering a 10 man crew of Conservation Corps workers to hold themselves ready for a fire call. Upon arrival at the fire, Mr. Cheyney discovered that it had been set by Mr. A. Frei, who was disposing of some slash on his place without securing a permit." (Six Twenty-Six)
