History of Eureka County
Eureka County was created in 1873. It was formed from parts of Lander County. This happened after people found a lot of silver more than 100 miles (160 km) east of Austin.
The miners in the new camp complained that Austin was too far away. They needed a closer place for official county business. So, a new county was made just for them.
The county got its name from the ancient Greek word "Eureka". This word means "I have found it!" It's a famous saying used when someone discovers something important. Eureka has always been the main town for the county.
