Metallic coal ?

[Bruce R]

Went to Centralia today, it was a bust. No matter how far back into the bush I went, I was hitting pull tabs. But the really weird thing was, I got several great hits but found nothing. I'd dig down 3 inches and stick the pin pointer in,and nothing. Sweep the coil and it's better than before. Go down another 3 and the pointer goes crazy, but all around the sides and bottom of the hole. Scanning my dirt gets me a hit but there's nothing there. Here's a pic of a rock that looks like coal under my magnifier, it's very light but sets off my coil and my pointer. What the heck is it ? The ground up there seems to be loaded with the stuff. I must've dug 10 holes that were 8-12 inches deep and found nothing, and whatever this is, it's all over up there cause I moved around to different locations. Any ideas ??View attachment 1317729View attachment 1317731View attachment 1317732View attachment 1317734View attachment 1317735View attachment 1317739

It sets off a detector ? That would be a drag cause Centralia seems to be loaded with it and I can't seem to tune it out.

"Hot Rock"

I find them in my area, too.......I pull 'em take them home and put them around the perimeter of my garages..........
Had to dig several 2+ foot holes for concrete to support the front and back porches......I pulled buckets of rocks and stones out. To find a use for them, I made a wall of larger rocks 12" out from the walls of the garages and lined the interior with smaller stones for the rain to drip into.........those "beepers" do no harm in there..........

Coke burns much hotter than coal , used in industries to make steel. Pennsylvania was the steel capital of the world once. and yes it sets off detector.

Possible iron crystals. I've seen them form under a metal chop saw and behind the wheels of a train like snow builds up behind the wheels of your vehicle. In this case, the metal grindings are flying off hot and kind of fuse together and build up to a weird shape metal object, but I guess there's other ways these things form also.

That stuff is all over up there. I find it in Lansford and Ashland too, as well as coal that sets off my detector.

Again, it's Coke.

Found lots of holes dug up there, even one 3ft x 3ft x 2 ft deep, l scanned the bottom of it and got a hard hit but after digging another 8in. I gave up. I think someone else was chasing phantom signals too. Also, I saw the bottle diggers had been everywhere.

I found one the other day. No coal around here but there is iron ore. Just a hot rock

I kinda clued in on the third hole when I realized it was deeper than my detector could go.

Hey Bruce, does your pin pointer go nuts in the hole?

Yes it does, I keep thinking I'm missing the target so I widen the hole, still nothing. I'll have a hole big enough to bury a 1 gal. jug , I stick the pointer in dead center and it starts going off about half way down, 3 inches away from anything. I test it on my trowel and need to get within an inch or so.

Someone told me that there may be a large target below it. I ended up with three just alike. I will use a mini escavator to do that much digging.

Could the ground be magnetic ? Is that possible ?
