Hot Rocks and Deviant Behavior.:laugh:

I've had a few PM's about Hot Rocks and how they can make your life miserable. So I thought I would post a few pix of a typical Hot Rock I have in my area and it's Deviant Behavior.:lmfao:

In the first photo is a compass on my deck as a reference point. Notice how my decking almost lines up perfectly N<>S, I'm really into that FunSway stuff, really I am. :rofl:

And yes for you FunSway perfectionists I did try to account for the Magnetic Declination. :rofl:

Reference photo:

Next the Hot Rock causing the compass needle to Deviate about 100 degrees to the right, notice the curved edge of the rock it points at. Looking to the left ~260 Deg, you can see some rust stains.

And now with the curved edge of the rock pointed South, the rock Deviates the needle 180 degrees.

I hope this little demo lets the less experienced "see" the effect of mineralization present in the ground matrix in a visible & practical way. Because this is what the electronics in your detector is seeing and trying to negate the effects of.

I can remember the first time I, "hit" a hot rock. Kept looking for a coin or something. First is was here, then over there. Then, what the h###. It was that little rock I kept pushing around!!!
 
I used to live in Jackson Hole, WY, and there is a ghost town about 60 miles south of there in Idaho. It is an old gold mining camp, and the rocks from which the gold eroded look like the picture in this post. It is andesite porphory. The rock in the ghost town I mentioned has large phenocrysts of hornblende, magnetite, and hematite. It is hot rock hades! Back in the 90's the technology was not as advanced, and I simply could not balance out the "hot" ground enough to be successful. I don't live near there now, but with today's technology, I might take a trip with my Xterra, and a couple of other gold detectors I have, and give it a shot. I had never thought of using a compass to experiment with magnetic interference. That's a good demo, Bill.
 
OGD and chocolate don't mix either... How gauche! :rofl:

Try some Framboise next time Bill! :poke::cheers:
