Metaphor: The Tree of Utah, sometimes called the Tree of Life, is an 87-foot-tall (27 m) sculpture that was created by the Swedish artist Karl Momen in the 1980s and dedicated in 1986. It is located in the desolate Great Salt Lake Desert of Utah on the north side of Interstate 80, about 25 miles (40 km) east of Wendover and midway between the former railroad communities of Arinosa and Barro. The sculpture, which is constructed mainly of concrete, consists of a squarish 'trunk' holding up six spheres that are coated with natural rock and minerals native to Utah. There are also several hollow sphere segments on the ground around the base.
