The Nobles Emigrant Trail, also known as the Fort Kearney, South Pass and Honey Lake Wagon Road, is a trail in California that was used by emigrant parties from the east as a shortened route to northern California. It was pioneered in 1851 by William Nobles, who discovered an easy shortcut between the Applegate Trail in Nevada and the Lassen Trail in California. The trail was extensively used until the 1870s, when it was superseded by railroads.
