George Horatio Derby, better known as a brilliant humorist, was a trained topographer and produced several maps of major importance.

A map of major importance to the California Gold Rush. On a scale of 4-1/2 miles to the inch, it provides a detailed view of the region with numerous small towns, ranches, Diggings (including Mormon and Dry), trails and roads. Interesting notations concern grazing, road conditions and soil fertility. This early look at the Gold Regions locates Sacramento City just south of the American River (as a simple grid pattern), Vernon, Fremont, Sutter and Green Spring.
