April 11, 1920: "Two school teachers, Miss Cora Crosby, Bellingham, and Miss Thompson, Everett, have been named to serve this summer at a lone fire lookout station on Sourdough mountain, north of here. A lookout 'cage' or cabin, located at an elevation of 7,000 feet, will be occupied by the girls. Steel cables extending over the roof, anchor the cabin to the rocks so that winds will not hurl it down the mountainside." (Twin Falls Chronicle)
June 1925: "There is still a great amount of snow in the mountains and the streams have been unusually high for the past month. The Sourdough Lookout Station building was not visible on May 18, being still covered with snow." (Six Twenty-Six)
August 1925: "Lookout Stations are of no value at present owing to dense smoke and low-lying clouds. Sourdough has been veiled for several days. An electrical storm passed over the district July 21, but so far as it is possible to determine, no fires have followed. T.T." (Six Twenty-Six)
December 1929: "Roy Abbott, our 'Sourdough' lookout who came up from Oregon State College last spring, has become so attached to the Mount Baker Forest that he declined to go back to College this winter. Roy says that he did not get enough of the Mount Baker during the summer as he was not permitted to amble away from his post on top of Sourdough during the summer months, and what he could see lots of country that lured him to it. Therefore, he purchased a string of traps and Miles Garratt's claim to both Big and Little Beaver Creeks as his trapping ground. He has traps and provisions all out on line so that soon as season opens, a December 1, he intends to run the marten and other fur-bearing animals a merry chase for at least two months. At present he is working at Diablo. In order to get himself in shape for his trapping season, he took a jaunt to southern Oregon on shanks horses. When he returned he was asked what kind of trip he had, etc. He said the walking wasn't bad as he caught a few rides, but the rides seemed to be awful short and walks long. Thomas Thompson" (Six Twenty-Six)
