Before the California Gold Rush of 1849, the indigenous Mountain Maidu were the primary inhabitants of the area now known as Plumas County. The Maidu lived in small settlements along the edges of valleys, subsisting on roots, acorns, grasses, seeds, and occasionally fish and big game. They were decentralized and had no tribal leadership; most bands lived along waterways in and around their own valleys. Areas with high snowfall, including the Mohawk and Sierra valleys, were hunting grounds for game in the warmer months.[3][4]
In 1848, European Americans discovered gold in the Sierra foothills. Miners were attracted to Plumas County in particular, largely due to the tales of Thomas Stoddard, who claimed to have discovered a lake lined with gold nuggets while lost in the wilderness. Gold-hungry prospectors flooded the area. Though hopeful miners scoured the glacial lakes (now designated as the Lakes Basin Recreation Area) for months, they did not find the purported lake of gold. But some had success panning for gold in the rivers and creeks in the area, and created squatters’ villages, the first non-Native American settlements.[5]
Rough shanty towns quickly sprang up around successful mining areas, including Rich Bar, Indian Bar, and Rabbit Creek (now La Porte). Many were developed adjacent to the Feather River, named Río de las Plumas by Spanish explorer Captain Luis Arguello in 1820.
In 1850, 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 from Western Nevada through much of Plumas County, eventually terminating in the Sacramento Valley.[6] Many erstwhile miners followed this trail 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. Between 1851 and 1854, the Beckwourth Trail was frequently traveled, but in 1854, use dropped sharply when it became a toll road. The toll to move a ton of freight from Bidwell Bar to Quincy was about $18. This made using the Beckwourth Road an expensive enterprise and use of the Beckwourth Trail declined. [7]
