This detailed map of Mexico, Texas, and the American Southwest is one of the earliest detailed maps of the region. Based largely on Von Humboldt's important map (1811), it was published for an American audience at a time just prior to Austin's arrival in Texas. The settled parts of Texas are confined along the Gulf of Mexico and the Rio Grande River, with the northern area blank except for a few rivers and the Spanish Trail from the Red River to Santa Fe. The northern portion of the map covers the little-known parts of present-day Utah, Arizona, and New Mexico. It shows several fictitious geographic features in the Great Basin, and notations that were compiled by the Escalante expedition of 1776-77. The Santa Cruz River of southern Arizona is still not shown, and Tucson is misspelled Tubson. The map identifies topographic features, mines, presidios, military posts, and Native American inhabitation. The title within the map is Mexico and Internal Provinces. It is flanked by text containing economic, political, social, and historical data. Size with text is 20.6 x 16.6". The map was drawn by J. Finlayson and engraved by Young and Delleker.
