Bottom picture is the US/Mexico border and houses at the outskirts of La Rumorosa on the other side of the wall. You can see the wall continues down to the left in the photograph.
Taken with a Mamiya RB67 (negative is 6 cm x 7 cm), processed and scanned by the good folks at North COunty Photographic Services (http://www.northcoastphoto.com/). Very little, if any post-processing was done to these images.
