Excerpt from Geologic Reconnaissance of a Part of Western Arizona
The northern third of the region is covered by the early reconnais sance maps of the United States Geological Survey, and the geographic features are well known. Little has been done, however, toward accurately mapping western Arizona south of the thirty - fifth par allel. The maps heretofore published were found erroneous, espe cially in the locations of mountain groups and lines of drainage. It is not claimed that the map accompanying this bulletin is errorless, but in the southern part, where previously published maps have been most incorrect, this map is believed to be measurably accurate owing to data acquired by recent railway surveys and furnished for use in this bulletin by W. A. Drake, engineer of the Santa Fe Rail way system.
