1834. Mr. Greenhow, in his History of Oregon and California, states that the Anahuac Mountains is “the appellation most commonly applied to this part of the dividing chain extending south of the 40th degree of latitude to Mexico,” but when and on what grounds that name has come to be so applied, he does not explain. Anahuac was the denomination before the Spanish conquest of that portion of America which lies between the 14th and 21st degrees of north latitude, whereas the Cordillera of the Mexican Andes takes the name of the Sierra Madre a little north of the parallel of 19°, and the Sierra Madre in its turn is connected with the Sierra de las Grullas by an intermediate range, commencing near the parallel of 30°, termed La Sierra de los Mimbres. The application, indeed, of the name Anahuac to the entire portion of the chain which lies south of 40°, may have originated with those writers who have confounded Anahuac with New Spain; but as the use of the word in this sense is incorrect, it hardly seems desirable to adopt an appellation which is calculated to produce confusion, whilst it perpetuates an error, especially as there appear to be no reasonable grounds for discarding the established Spanish names. The plateau of Anahuac, in the proper sense of the word, comprises the entire territory from the Isthmus of Panama to the 21st parallel of north latitude, so that the name of Anahuac Mountains would, with more propriety, be confined to the portion of the Cordillera south of 21°. If this view be correct, the name of the Sierra Verde may be continued for that portion of the central range which separates the head waters of the Rio Bravo del Norte, which flows into the Gulf of Mexico, and forms the south-western boundary of Texas, from those of the Rio Colorado, (del Occidente,) which empties itself into the Gulf of California.

The Rocky Mountains, then, or, as they are frequently called, the Stony Mountains, will be the distinctive appellation of the portion of the great central chain which lies north of the parallel of 42°; and if a general term should be required for the entire chain to the south of this parallel, it may be convenient to speak of it as the Mexican Cordillera, since it is co-extensive with the present territory of the United States of Mexico, or else as the Mexican Andes, since the range is, both in a geographical and a geological point of view, a continuation of the South American Andes.
