Neat pic, I to have had to stop and take a pic of it when I saw it down here in SC. I was at a state park when I noticed the little city of sand. Mine is not as large as yours but still neat thats for sure. It's amazing at what nature does.
LOL rmpt...naw, it's a close-up of little sand towers. I took the pics at a site that's suppose to be an Indian settlement and/or a ceremonial/burial mound location.
I hang out there before another cool place to hunt is gone due to "progress" or construction of new homes (please note the sarcasm in that statement) wipes it out.
