Very unusual thing, a support wall of junkyard cars to brace an airfield boundary from runoff water corrosion

the location is only told as Southern California, and that the airfield was used because the location is so remote. http://www.thegentlemanracer.com/2012/02/lost-california-great-wall-of-cars.html

I've posted a similar riverbank of junkyard cars a couple years ago, I've no idea how to find that post though
