Plumas County, California, United States (39.94310 -120.80595)
In 1850 notable African-American frontiersman James Beckwourth discovered the lowest pass through the Sierras, which became known as Beckwourth Pass. Using the pass, he blazed a trail that began in Western Nevada and went through much of Plumas County, eventually terminating in the Sacramento Valley. This trail was followed by many erstwhile miners into Plumas County. Beckwourth also set up a trading post in the western Sierra Valley that still stands today. Though the Beckwourth Trail was longer than the original emigrant trail that ran south of Plumas County, its lower elevations extended its seasonal use when the higher trail was snowbound and impassable. The Beckwourth Trail had heavy use until about 1865, after construction of the transcontinental railroad, when railroads became the favored transportation method for westward-bound travelers.
