Migration
Early migration routes to and from for emigrant settlers included:


 * California Trail 1844 to 1869 from western Missouri to northern California
 * The Lassen Cutoff 1848 was established by gold rushers from Oregon going to California. It branched off the Applegate Trail at Davis Creek, went through Devil's Garden to the Pit River passing east of Mt. Lassen, and turning west to Lassen Rancho, California, and from there to Sacramento. In some years as much as 1/3 of emigrants mistakenly took the Applegate Trail-Lassen Cutoff, a much longer and more difficult trail than the Truckee or Carson routes.
 * Beckwourth Trail 1850 left the Truckee Trail near present-day Sparks, Nevada going to Oroville and Marysville, California
 * Nobles Road 1851 from the Applegate Trail at Rabbithole Springs in the Black Rock Desert of Nevada to Shasta City, California
