As detailed in my last post, Border Patrol agents use sign cutting to track anyone crossing the international border including migrants seeking job opportunities in the United States or drug smugglers moving their narcotics across Arizona’s Sonoran Desert in the Southwest.
Sign cutting was not devised by American border enforcement. The history of sign cutting dates to a period long before modern civilization, when humans had little in the way of protection from the natural elements. In addition to shelter and fire, food represented the most basic need. Hunter-gatherers would track creatures such as mammoth and elephants for long periods of time.
