Notes: Paul Zahl, also known as Twin Tower, is the world's 17th tallest tree, the 6th tallest tree in Redwood National Park, and the 2nd tallest tree in Tall Trees Grove. The tree was named to honor National Geographic Society senior scientist Paul A. Zahl who, in 1963, discovered Howard Libbey, then the world's tallest tree, in Tall Trees Grove. Zahl's discovery, featured on the cover of the July 1964 issue of National Geographic magazine and in an article in the same issue entitled Finding the Mt. Everest of All Living Things, led to the creation of Redwood National Park in 1968. Paul Zahl is also the 22nd fastest-growing redwood yet measured; it grew an average of 21.7 ft3 (0.62 m3) and 650 lb (295 kg) each year over a recent decade.
