Migrants’ Shelter — Buenos Aires National Wildlife Refuge 2007

The Sonora Desert is char­ac­ter­ized by cli­matic ex­tremes. In the sum­mer months, tem­per­a­tures reg­u­larly reach 37–49º Celsius (100–120º Fahrenheit). Migrants of­ten build shel­ters that blend into the land­scape to shield them from the sun and avoid de­tec­tion by Border Patrol he­li­copter patrols.
