Disturnell’s Treaty Map


p. 16. Schwartz & Ehrenberg, Plate 170 (illustrating an 1847 edition) & pp. 274-76: “This

map was attached to the 1848 Treaty of Guadalupe Hidalgo, which ended the Mexican

War and subsequently added California,

New Mexico, Arizona,

Nevada, and Utah to

the United States.... The boundary of the United States is depicted as the Rio Grande in

the east and the parallel of 32°15


north latitude in the west. This caused San Diego,

which lies just north of this line, to be included in the California territory claimed by the

United States.” Taliaferro 283 (citing an 1846 revised edition and quoting Lawrence

Martin): “The map actually became part of the Treaty [of Guadalupe Hidalgo] and has


gured prominently in settling border disputes.”


Mapping the Transmississippi


#507 & Vol. III, pp. 35-36: “[Mitchell’s 1846



Oregon and


] and

Disturnell’s [map]

were among the





maps of the year [1846].... [Disturnell’s map] displayed certain signi



items not present on the White,

Gallaher and White map of 1828, from which it was

taken. In the


rst place, the Alta California area, which included the Great Basin, was

largely modeled on Frémont’s map of 1845, and the Great Salt Lake was copied from it.

The Monte de Oregon still appears, however, crowding Frémont’s Old Park and New

Park, and farther south is the Cumbre de Jaime (James Peak) on the site of Pike’s Peak.

Moreover, on the Disturnell’s 1846 map the boundary of the United States is given as

the Rio Grande, and other data respecting current and earlier Texas boundaries are


Near the mouth of the Rio Grande, Ft. Brown now appears, with ‘Gen. Taylors

Route 1846’ nearby. Another change took place farther west, of which Martin says: ‘An

engraved boundary between Alta California and Baja California extends east and west

near the parallel of 32°15’ north latitude, from a point on the Colorado River about 50

miles south of the Gila to a point on the Paci


c Coast about 50 miles south of San Diego.

This boundary was not present on the White, Gallaher &White map, which has in color

but without an engraved line the same northeast-southwest boundary between Upper

and Lower California that appears as an engraved line on the 1846 and 1847 editions of

the Tanner map, the 1826 edition of which was the source of the...editions published by



& White or by

Disturnell. It is a debatable question

whether, if

Disturnell had engraved this northeast-southwest boundary upon his map in 1846, as

Rosa did in his plagiarism of Tanner’s map in 1837, the southern boundary of the Untied

States at the Paci


c might have been


xed some 120 miles south of San Diego rather than

only a little over a dozen miles south of that city.’” Wheat,

John Disturnell was primarily a businessman rather than a cartographer. As events of

the Mexican-American War developed and as changes occurred, he incorporated dates

and places in new issues of his map without comment. Between 1846 and 1849 over

twenty variants of his map appeared. The Disturnell Treaty Map was not an o


cial gov-

ernment publication—it just happened to be the map that Nicolas P. Trist took with him

when he was sent as peace commissioner to Mexico in 1847. It was the map’s inaccura-

cies in locating El Paso and the Rio Grande, rather than its correctness, which made it

historically signi


cant in U.S.-Mexican relations.

It might be argued that the Disturnell version of the Treaty Map (particularly the


rst printing and the seventh and twelfth editions) is the most historic of the various

maps in the Treaty Map sequence. It would seem that an example of Disturnell’s map

would be the least di


cult of the sequence to acquire, since Disturnell published over
