After leaving Altar, migrants face a variety of threats, like drug cartels, bandits, the environment and US Border Patrol. They often get lost or disoriented in the desert and depend on the Border Patrol, or Mexico's Grupo Beta, to find them and save them from dehydration or hypothermia. The ones who are picked up by the border patrol are usually deported or repatriated to Nogales, Sonora, where they will rest up and prepare for their next attempt at crossing.

Once a sleepy agricultural town, the entire economy of Altar, Sonora is, at this point, based on human smuggling. Sitting just an hour drive south of the Arizona-Mexico border, Altar is the last and most critical stop before migrants take to the dangerous desert crossing.
