Just because you don't live in an area with iron mines doesn't mean your soil isn't "irony".:smile:

If you live in the iron/rust belt of the Central U.S. you know you have iron problems. If you live in the South East you will find out about iron rich clays which are easy to spot. Likewise in Gold Country the Black Sands are well known & understood to be a problem.

But there is an insidious type of iron soil that you may run across in sedimentary areas and not recognize................the dreaded Bog Iron.

Be careful out there when you're hunting around the Big Muddy, the Swamp Thang(Bog Iron) lurks!

Sure wouldn't wanna get....BOGGED down in THAT! On a more serious note, I've had some chunks of clay around here ring out with various tones. Numbers fluctuate, but every time I start looking for whatever set the detector off...it's just a chunk of clay. Not so much when it's dry by the way-the clay has to be wet.

there was a spring on granpa's back 40 where the vegetation was stained bright yeller from the runoff. One day while digging around damming up the creek we found some heavy heavy yeller rocks. Man them was heavy, too heavy to carry back to the house so we burried them for later but I forget where.

Bog iron from rust stained water... Hmmmm!! Sounds like a mega millenia time frame type thing and in country that saw the repeated advance and retreat of glaciers over time it jus don't add up in my book

Ima gettin sceptical in my ole age.

Just to keep it in the spirit of a metal detecting forum I guess Ishould get out looking for those yeller stones.
