i bet if you nation treasure 2'd those rocks they'd have alien writing on them.
everyone knows that rocks are the most technologically advanced things that alien races can leave behind as markers.
I wouldn't worry about pebbles, its the 100+ ton rocks that where "placed" with a precesion we cant match today that are real spooky.
