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.
Taapaca
The term "tara paka" is Aymara for "two-headed eagle" or "winter (prey) bird", and Quechua for Andean eagle. It is also known as Nevados de Putre; sometimes "Nevados de Putre" is used to refer to the volcanic complex and "Taapaca" to its highest summit. The term "taapaca" may also be the origin of the term "tarapaca" and could be an Aymara name for the founder deity Viracocha. "Putre" in turn appears to mean "sound of falling water" in Aymara.
