This map of Mexico was included in Pike’s landmark report of the Southwest, describing his expeditions from 1805-1807. His book is one of the most important of all American travel narratives, and stands alongside those of Lewis and Clark as a cornerstone of early western exploration. The report itself includes accounts of Pike's travels to find the headwaters of the Arkansas and Red Rivers, his explorations along the Mississippi River, and his Spanish escort to Santa Fe, New Mexico and Chihuahua, Mexico.

Contained within the report are six maps including this one, which covers the area from Zacateca south to Oxaca and depicts the internal political boundaries, or administrations, and their capitals. Roads, towns, villages and Indian villages are depicted as well as numerous evacuated towns. At top is the boundary line dividing the Vice Royalty from the Internal Provinces.
