Scarce map of the United States, published by Cowperthwait, Desilver & Butler.
The map shows some of the most unusual US territorial configurations.
Oregon Territory and Washington Territory run from the Pacific Ocean to the Rocky Mountains, immediately after the creation of Washington Territory. Large New Mexico and Utah Territories appear for the first time, having just been established as territories in 1850.
A strange notch incorporates Middle Park in Colorado into Utah. Massive Nebraska Territory extends to Canada and the Rocky Mountains, just north of the oversized Kansas Territory. Texas is filled with early roads, including Road from Ft. Smith to Dona Ana made by General Arbuckle.
The Great Spanish Trail to Salt Lake is shown, as is Fremont's route. Lewis & Clark's route is noted. Many Indian tribes and early western forts. Large inset of the gold region in the year following the discovery of gold in California.
