Hanging in the lobby of the Seattle Art Museum is this 105-foot long tree sculpture by John Grade. Grade first made a plaster cast of a living 140-year old western hemlock growing along the Middle Fork (hence the name) of the Snoqualmie River east of Seatle. Then he along with hundreds of volunteers used the plaster mold to recreate the form of the tree from thousands of pieces of reclaimed old-growth cedar.
