A terrific map published at a time when many territorial borders were at their most unique configurations. Utah is a large territory that includes all of Nevada and most of Colorado. New Mexico extends between Texas and California, but Arizona Territory occupies it's southern half. Most likely this is showing the Confederate Territory of Arizona as established by the Confederate General Baylor. Oregon state has just been formed, leaving its eastern half to Washington Territory, which is now shaped as an upside down "L" and touching Utah in the south. Nebraska extends from Kansas to the Canadian border and includes today's Montana, Wyoming and much of the Dakotas. Oklahoma is Indian Territory. Dakota is a small area between the Missouri River at the west and the Sioux and Red Rivers on the east, and bounded by Nebraska and Minnesota. Extensive railroad network throughout the East, with proposed railroads, wagon roads and emigrant routes shown in the western territories. Inset of Newfoundland in the Atlantic. A decorative grapevine border surrounds this attractive map. First edition most likely published in 1861.
