Before Polaris made it’s brand famous, there once as a town in Yuma County that shared that name. Polaris’ post office was established June 17, 1909 and was discontinued July 31, 1914. Felix Mayhew discovered the outcropping responsible for Polaris and sold it for a cool $350,000. Polaris was named for the North Star and significant because of the North Star Mine. It was reported there was about 150 residents. The mines played out in 1911. The mining town of Polaris is in the Kofa Mountain Wildlife Refuge. No remains of this ghost town were left.
