Very interesting theory Lostlake. I always had that as a theory also, but never added up any tallys or boxes! I really dont think the natives were just doodling on rocks! There is some purpose for the cross hatching seen on MANY upon MANY artifacts!lostlake88 said:I always thought these curious inscriptions were a form of calender. Many show 12 notches (12 months) and then describe the equinox and soltice, but not by squares but by intersecting lines. Interestingly enough many of them add up to 180 days plus or minus a few. crackpot out...Click.
