History
Eureka County was established in 1873 and formed from Lander County after silver was discovered more than east of Austin. The new mining camp's residents complained Austin was too far to go for county business and a new county was created. It was named for the ancient Greek term, Eureka, meaning, "I have found it." This term was used earlier in California and other locations. Eureka has always been the county seat.
