Even this early in the morning, temperatures near this 3,500-foot peak reach triple digits, with this part of the U.S.-Mexico border under an excessive heat warning.
Volunteers with Borderlands Relief Collective, a group of private citizens from the San Diego area, are preparing to drive up the mountain and deliver water and first aid to migrants crossing into the U.S.
Almost as soon as they start climbing up, the group encounters a man sitting on the side of the road. He breaks into tears when he sees the volunteers approaching with water.
He is dehydrated and wearing shoes too small for his feet. In broken English, he says his name is Taleb, and he’s from Mauritania. Before NPR can get a last name, he’s rushed aside to receive care.
