amazing again dsty. i think you nailed it again. the photos that i just recently posted on this thread,are east,and on the shorter range est, i bet the 1380 is real close to the sweet spot. i found some smaller stones at about that distance that i have found at other sites,diffently shaped by man. how you ever knew it was a tunnel too,is unreal,great call again. for if you go down on the ground at the base of the stone shell, there is a arch way tunnel all the way thru the stone shell, running east and west. great call, and dsty,you knocked it out of the park again. the sun F is over there + what i call the bull shape on the one stone. just scroll back, look at the photos,they are east of there,at about the 1380 mark. man dsty,you looked at that one stone hole and pulled all that info., killer dude,just killer, thanks. good stuff.
