A great map of the United States with early western territorial boundaries. Minnesota includes most of present-day North and South Dakota, with Nebraska taking in the rest of the region up to the Rocky Mountains. Kanzas Territory borders Utah and New Mexico in the west and there is no Colorado. Washington and Oregon both extend eastward to the Rocky Mountains and the Continental Divide. Utah and New Mexico are both shown in their largest configurations. Several exploration routes are shown, including Fremont, Marcy, and Kearney. Dated 1855, but most likely published in 1857. Map is encapsulated in archival Mylar.

A soft crease next to centerfold, a few spots in margins and the right paper edge is a little rough. Map image is very good.
