1939: "During the year, the High Rock Lookout was discontinued, and the Snoqualmie Lookout erected. The High Rock territory is now largely overlooked by the Blue Mountain Lookout, erected a few years ago by the S & P CCC crews. The Snoqualmie, which is the intersecting lookout point in conjunction with Blue Mountain in Snohomish County, is some 12 miles south of High Rock. A 60 foot tower, constructed of Douglas fir piling was erected on Section 9, Township 25, Range 8 East. It proved in its first year to be a most serviceable point. The lookout man was housed in a tent, as a temporary measure. During 1940, it is expected that a 12 x 14 cabin will be erected on the peak for his use." (32nd Annual Report of the Washington Forest Fire Association)
1940: A new Ranger cabin was built at Snoqualmie Lookout. (33rd Annual Report of the Washington Forest Fire Association)
October 16, 1943: Aircraft Warning Service Station 'Dog 5-5' was deactivated. An existing structure used as a fire lookout was used as the observation post. The Service added a 12 x 20 garage using AWS funds to complete the improvements on the site. At the end of service the site was retained by the State for fire detection.
