The "King Clone" creosote ring is one of the oldest living organisms on Earth.
It has been alive an estimated 11,700 years, in the central Mojave Desert near present-day Lucerne Valley, California.
This single clonal colony plant of L. tridentata reaches up to 67 ft (20 m) in diameter, with an average diameter of 45 ft (14 m).

King Clone was identified and its age estimated by Frank Vasek, a professor at the University of California, Riverside.
 Measurements of the plant, as well as radiocarbon dating of wood fragments, were used to determine the plant's mean annual growth rate outward from the center of the ring.
 By measuring the diameter of the ring, its total age could be estimated.
 It is within the Creosote Rings Preserve of the Lucerne Valley and Johnson Valley.
