very interesting read, james. i had discovered some pictures of this a couple of years back, & did some reading on it at that time, too. wind seemed to be the prdominant explanation, but there was not anything super-concrete about that theory either. that's why i wanted to ask someone that had actually been there if they could actually see them move. i had forgotten that everything i had read stated that noone has ever seen them actually move. i love it when God places things in nature that can't be explained. the world is a vast & beautiful place - so much to take in & enjoy & appreciate. i can't say if i'll ever make it to this spot on the earth, but i enjoyed seeing it thru your eyes & experience. thanx for the pictures & for this link.
