This historical marker groups together four different historical sites. These include sites that now encompass the Plumas-Eureka State Park. Most of these towns have few residents or have completely disappeared.
For example, Johnstown, now Johnsville, was founded in 1876 and now has around 12 residents. Jamison City has completely disappeared. Jamison City was a mining town and became famous after a 52-pound gold nugget was discovered in the Eureka Quartz vein.
The vein was first discovered in 1851 and would eventually yield $17 million in gold. The Plumas-Eureka and Jamison City mines would continue to be used until the early 1900s.
