athometoo, I'm no rock expert but it sure looks like welding slag. All we have around here is lava rocks but I do a lot of welding. What size pieces are they?
ran a few more tests , hammer test = cracks up . rosebud torch = strong sulphur smell and evaporates . steel file = sparks . final conclusion = its gold , just the wrong kind . sure is pretty though . we just got 8 inches of rain and the river is swollen , wait a coupla weeks and go back and pick up the rest . and a little bling to my rock garden . plus i have given some to the neighborhood kids . they think its cool too . sam sorry sizes are golfball to raquetball size although some resemble large dog droppings . kinda like the goose and golden egg[]
You want to sell me a bagfull of those bad boys? No need to clean them either! There are probably some good fossils in there too, hidden deep below the grasp of rock-hounding landlubbers like myself.
Which reminds me, when i was young (8 and younger) I lived in Maryland and my father would take me out to the Chesapeake to hunt for Miocene shark teeth and other fossils. This one outing, I see these 2 scuba divers emerge from the murky deep with a mesh bag filled with gigantic megladon teeth and interesting fossil bones, ranging from 2 to over 5 inches (probably 30 spectacular teeth they had), and in awesome shape too. I could hardly believe it, and the stories of the large items they had to leave behind were insane. Made my little <3/4ths inch teeth seem like peanuts. []
The bay is good for fossils but if you want to find really nice ones you need to go down to the phosphate mines in NC. The shark's teeth are still razor sharp when you find them.
