Geo...here at the lake that i live on, one of my friends and his wife were walking along the bank since the lake had gone down so much, they started finding arrow heads after arrow heads, just laying there at the edge of the water. One evening they were out there walking the shoreline, looking for arrow heads, and he sees what looked to be a spear head sticking out through the sand, sure enough, thats what it was. So he goes and gets his shovel and started digging, and just below the sand, under where this spear head was found, he uncovered 31 spears heads, all just laying there, stacked so nice and neat on top of one another. I cant even begin to imagine what the thrill of that find must have been like. 31 spear heads from one hole!
