Map of the Sacramento Valley detailing an important California route and the demise of Captain William Warner.


Highly detailed and historical important map of Warner’s Route, one of the most important early routes from San Francisco and the gold regions of California to Goose Lake and the Oregon Trail.

William Horace Warner (8 May 1812 – 26 September 1849) was an officer in the United States Army’s Corps of Topographical Engineers. In 1849, he led an Army survey party north from Sacramento through the uncharted country of northeastern California into south central Oregon. Warner was killed by Native Americans in northeastern California, just south of the Oregon border. In the mid-nineteenth century, two army outposts in southern Oregon were named after Warner. Today, the Warner Mountains, Warner Valley, and a number of other landmarks bear his name.
