"A New Map of the State of California, the Territories of Oregon, Washington, Utah & New Mexico", Thomas, Cowperthwait & Co.

A great map of California and the large western territories from this important series of maps originating with Samuel Augustus Mitchell. The map is filled with early territory and county configurations, the exploration routes of Lewis and Clark, Fremont, Kearney and Cooke, and the Spanish and Oregon Trails. Washington and Oregon have their eastern boundaries at the Continental Divide in the Rocky Mountains adjoining Nebraska Territory. Their county development is confined to west of the Cascades except for the newly formed Skamania and Walla Walla counties. Utah Territory extends to Middle Park and Long's Peak in present-day Colorado where it borders Kansas and Nebraska Territory. Denver does not yet appear nor do any of the early mining settlements to the west, however St. Vrains Fort is located. New Mexico Territory encompasses parts of present-day Colorado and Arizona and shows the Gadsden Purchase border with Mexico. County development in California is well underway except in the south where the huge counties of San Diego, and San Bernardino dominate. Decorative scroll borders in the characteristic green color. Dated 1850 but with information current to at least 1854.
