Good luck to any illegal trying to cross this most inhospitable territory of vicious cactus especially the Cholla (bottom photo) which punctures your clothes and skin as I found out to my demise and horror! Illegals follow "social trails" which are not at all like the easier hiking trails we tramp. In addition there are rattlesnakes, coyotes and other threats waiting including border patrol agents on ATV's. Note third pix is the park namesake Organ Pipe Cactus.
