(OK BUT YOU NEED TO REALIZE HOW THESE ARE FOUND
WHEN THEY EXPECTED TO DISPOSE OF THESE CHIPS THEY WOULD DUMP THEM ON THE GROUND AND POUR CONCRETE OVER THEM SO MOST OF THEM FOUND WERE ON TOP OF THE CONCRETE BUT SOMETIMES THEY WERE MIXED INSIDE THE CONCRETE DEPENDING ON HOW AND WHERE THEY POURED THEM
IVE EVEN DISSOLVED THESE ROCKS AND FOUND 10-15 CHIPS IN THE MIDDLE OF THE ROCKS
BUT THESE CHIPS DONT SELL FOR MUCH OUT OF THE ROCK SO ITS EASIER TO SELL THEM INSIDE OR ON THE ROCKS SO I BOUGHT A NUMBER OF THESE FROM THE GUY WHOS BEEN DIGGING AT THE SITE HE DOES DO A GOOD JOB AT CLEANING THEM WHILE STILL ON THE ROCKS)

MAYBE IT WAS SOME FROM THE CLUB WHO DUG THEM OUT ????? I STILL SAY ALL CHIPS THERE AT THE SAME DEPTH OR HEIGHT I DONT KNOW IF IM SAYIN IT RIGHT THEY ARE ALL AT THE SAME LEVEL AND NO CEMENT UNDER THEM AT ALL THEY LOOK ATTACHED TO ME BUT THEN AGAIN IM NO AUTHORITY ON THIS SORT OF STUFF JMHO
