your right shortstack,there is a ton of signs out here,and i dont understand them.they left so many cut carved stones,i can see the old trails zig zagging up the mountains.the shadow signs,sun signs. but there is not a trace of tailings or metal,pottery,glass trash at all.but they left cut stones everywhere. once in awhile i do find a peice of quartz's on the ground.they where even smart enough to keep the trail going past the mines,no dead ends.they really hid the mines well.i see the ax cut stumps.and iam sure theres even more signs,iam just not good enough to see them all.i dont know if its thousand of years of mining and sign making on top of each other ,or what.wish i knew more about the ancient stuff,and had a eye for it. i just keep plugging away at it,and hope i can make a break thru some day. i want to try some full moon photo work some day too,to see what shows up.the moon and stars have been used for a long time iam sure as a way of being guided.thats why now i just look at it as,was it worked by humans.its just to much for me at this time to try and understand it all.
