Title continues "5th U.S. Infy. under orders from the War Department. Also a continuation of the emigrant road from Fort Smith and Fulton down the Valley of Gila." This is a most informative map of the region illustrating the explorations of Capt. Marcy, including inputs from Col. Emery's Boundary Survey, Capt. Sitgreaves' map, as well as those of A.B. Gray and J. de Cordavas. It details the area from the Mississippi River to the Colorado, and from about 30° latitude north to the Arkansas River. North of the Gila the land is noted as Unexplored, with a legend reading: "In the vicinity of this place a tract of country is found which is said by several trappers to be exceedingly fertile, and abundantly timbered and watered." This erroneous note shows up a decade later on early maps of the Southwest by A.J. Johnson. Filled with a copious amount of important information and detail on Oklahoma, North Texas, and New Mexico. Locates exploration routes, Indian tribes, disputed territories, and much, much more. Wheat says this map is "one of the best of the period."
