This is a later issue of the map first published in 1834, which Wheat describes as "one of the foundation stones of western mapping history." This edition has been "revised and augmented" by Alexander Vuillemin and reflects the greatly increased physical knowledge of the region. It also reflects a slightly out-dated political view with the Gila River shown as the the U.S.-Mexico boundary. The Route des emigrants en Californie is traced from Jefferson, MO to the gold fields in California with an interesting deviation through Nevada. The map has considerable information on the Indian nations and early settlements in the western part of the United States. There are two large insets of Mexico, with one centered on Mexico City and the other depicting the Yucatan and Guatemala. Dissected in 21 sections, mounted on linen and folded, with publisher's label on verso, as issued.
