This photo is of the newly constructed border wall in the Altar Valley, adjacent to the Buenos Aires National Wildlife Refuge (NWR). It is approx. 7 miles long. 
There is a resident jaguar in the adjacent Baboquivari Mountains, and there have been numerous verified sightings of jaguars in the San Luis Mountains and on the Buenos Aires NWR over the past decade or so. This wall, and others like it that are imminent, obviously pose a threat to transboundary movement of this magnificent cat and its ability to re-establish in the US portion of its historic range.
