In the early 20th century, veneer plants in the Port of Olympia supplied surplus heat to a central plant that distributed steam heating to the area through underground pipes. The steam plant building is still in existence on Thurston Avenue. But this 1966 photograph from the Daily Olympian shows the dismantling of the plant’s smokestack, after the veneer plants were all shuttered.
