Johnson's series of maps of the American Southwest is one of the most interesting progressions in 19th century American cartography. The series was produced during a time of rapid westward expansion and changes in territorial boundaries. This edition includes the original four counties of Yavapai, Mohave, Yuma, and Pima in the newly organized Arizona Territory, with Tuscon as the capital. The Utah/Nevada border is now at 114°, and Arizona and Nevada have their final borders. Early historical details include the United States mail routes, the emigrant roads to California, the proposed railroad route through Utah, Nevada and California, and the Pony Express trail. Surrounded by a lacy border.

According to Ira Lourie's Johnson Map Project, this map was published in 1873-74 and reflects the addition of Mora and Colfax counties in New Mexico. Please visit his website for more information.
