King Clone was identified and the age estimated by
Frank Vasek, a professor at the
University of California, Riverside. After Vasek hypothesized that the creosote ring was, in fact, one organism,
Leonel da Silveira Lobo O'Reilly Sternberg (then a graduate student working in Vasek's lab), documented that plants within a ring had more similar characteristics than those from other plant clusters. Vasek then used two methods to estimate the age of the ring. One method counted
rings and measured the distance of annual growth, and the other used
radiocarbon dating on pieces of wood found in the center of the ring, and measuring their distances from each other and the living bushes. The two dating methods yielded similar results (age about 11,700 years). ==Public appearances==
