Accident my foot.  This is just more French passive-aggressiveness.

I imagine cannon balls are easier to pick up, you know, on the radar. I Imagine it's hard to actually, physically pick them up though. They must be heavy. When looking for graves and structure outlines it has a bad habit of showing stuff that ain't there and NOT showing stuff that is. I recall we couldn't guarantee a local tribe that GPR would 100% rule out graves on a particular site they wanted to build on. Just because the radar said there was nothing there dioesn't actually MEAN there's nothing there. They were, to say the least, perplexed by this. They just don't know where the HELL to put that new casino. LOL...

We were doing a survey of a site that turned out to be a military dump from the War of 1812, Sackett's Harbor on Lake Erie.

Organic stuff doesn't show up nearly as well on radar because organics are naturally stealthy. Once bone fossilizes, though, it's easier to pick up because it's largely no longer absorptive.

GPR may or may not show areas of disturbed soil, as well. It depends on the geology of the area -- soil composition and the like.

We got a lot of ghosts on the radar, and once excavation started there were a lot of things showing up that the radar didn't pick up.

As for picking up the cannon balls, well, I participated in track and field in high school, and our shot puts were essentially 12 pound cannon balls.

--- Quote ---We were doing a survey of a site that turned out to be a military dump from the War of 1812,Cool, sounds like a good site. I've found a lotta stuff but never a cannonball. I do have a friend that has metal detected a bunch of Civil War sites and has a few shells and cannonballs. I explained to him that the shells could still be live and he says,"They ain't blown up yet." I said, "Well, just don't try to take them apart to see what's inside." Imagine being a victim of the Civil War 140 years after the fact.

A better thread title would have been "Now THAT'S Bangers and Mash!".
