Wheat notes this is, all in all, an excellent map of the West that has a very early depiction of the Gadsden Purchase. It is one of the first commercial maps to show Jackson Lake east of the three Tetons. It shows the entire Western Country south of the Oregon Territory, borrowing heavily on the cartography of Fremont's maps of 1845 and 1848. Filled with place names including Mormon Station in Nevada, Franklin is opposite of El Paso and the New Mexican settlements are carefully named. Published by J.H. Colton & Co.
