Tenino
In the late 1800s a number of sandstone quarrying companies began shipping building stone, used in many regional buildings outside of Tenino, including the Old Capitol Building and the old Thurston County Courthouse in Olympia, the Mason County Courthouse in Shelton, Washington, Denny Hall and the Theodore Jacobson Observatory at the University of Washington, Seattle, the Pittock Mansion and the Pioneer Courthouse in Portland, Oregon and several post office buildings, including at The Dalles, Oregon. The US Government also used stone from these quarries to construct coastal jetties at Westport, Washington and elsewhere. The quarries declined in the early 1900s when many builders switched to concrete.
