For thirty years the Museum operated out of the Washington State Building. As with Forestry & California, this building was also a remnant of the 1909 Expo. It was the library until 1926 and then remodeled for the Museum in 1927. After the Museum moved out, it was gradually torn down, some in 1961 and the rest in 1988.
