The geography helps along with the National Park Service map for the California National Historic Trail. Remember that John first reappeared in Bridgeport, Nevada County, California. (And that's a different place than Bridgeport in Mono County, California.)
There were several trails over the Sierras as there were through the Great Basin. There were many bad choices because there was no good one. Yet please note that there is a direct route from Mormon Station (Genoa), Nevada to the Sacramento Valley. Follow No. 7, the Georgetown/Daggett Pass Trail to No. 5, the Georgetown Trail, and you end up in . . . Georgetown, just a few miles south of Bridgeport.
