Eureka, California
"Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as the state for its seal.
Eureka Spurs
The Eureka Spurs () are several rock spurs exposed along the east side of the head of Mariner Glacier, southwest of Mount McCarthy, in Victoria Land. They were so named, after the ancient Greek word eureka, by the Victoria University of Wellington Antarctic Expedition field party to Evans Neve, 1971–72, on the occasion of fossil discoveries made in the area.
