Certainly one of the lowest elevation stations in the Washington Cascades, Heybrook was developed in 1925 with a platform tower, replaced by a 45' tower with L-4 cab in 1932. In 1964, the present 67' treated timber tower was built with an R-6 flat cab. Promptly abandoned in 1970, volunteers worked on constructing a new cab during the late 1990's. The lookout may be added to the Recreation Rental program in the future.
