The Logan Elm that stood near Circleville in Pickaway County, Ohio, was one of the largest American elm trees (Ulmus americana) recorded. The 65-foot-tall (20 m) tree had a trunk circumference of 24 feet (7.3 m) and a crown spread of 180 feet (55 m).[1] Weakened by Dutch Elm Disease, the tree died from storm damage in 1964.[1] The Logan Elm State Memorial commemorates the site and preserves various associated markers and monuments.[1]
