HISTORY and MAP
Lassen County was formed on April 1, 1864 from parts of Plumas and Shasta counties following the two-day conflict known as the “Sagebrush War,” also called the Roop County War, that started on February 15, 1863. Due to uncertainties over the California border, the area that is now Lassen County was part of the unofficial Nataqua Territory and Roop County, Nevada during the late 1850s and early 1860s.
The county was named by European Americans after Peter Lassen, along with Lassen Peak. Lassen was one of General John C. Fremont’s guides, and a famous trapper, frontiersman and Indian fighter. He was murdered under mysterious circumstances near the Black Rock Desert in 1859.
By the 1880s small towns began to spring up all over Lassen County. Bieber developed at the north end of the county, in rich farm land. Gold was discovered at Hayden Hill, and the small town developed to support the miners. Hayden Hill no longer exists: when the mining stopped, the townspeople left for other communities. Madeline was formed at the north end of another rich farming valley, and along the railroad tracks heading north to Alturas, California.
