Cadillac Ranch is a public art installation and sculpture in Amarillo, Texas, USA. It was created in 1974 by Chip Lord, Hudson Marquez and Doug Michels, who were a part of the art group Ant Farm. It consists of what were (when originally installed during 1974) either older running used or junk Cadillac automobiles, representing a number of evolutions of the car line (most notably the birth and death of the defining feature of mid twentieth century Cadillacs: the tailfins) from 1949 to 1963, half-buried nose-first in the ground, at an angle purportedly corresponding to that of the Great Pyramid of Giza in Egypt.
