UNOFFICIAL EXTENTS OF THE REGION

Papers on the region describe geographic features that partly define it.

The United States portion of this region probably includes portions of Grant County, New Mexico , Hidalgo County, New Mexico , and Cochise County, Arizona . Major geographic features of the area include portions of the San Simon, San Bernardino, Animas, and Playas valleys as well as rivers of the same name.

QUOTATION

"If you're a scientist or work for an agency, you didn't get into it to submit to the kind of grief you get for what you're being paid. You have a feeling for the land - there's a pull there you can't resist." -Bill McDonald, Malpai Rancher
