#2I wonder what the tradeoffs are between ground penetrating radar and Muon tomography?

Muons scanning works for seeing through things, not into them. There are no muons coming from underground because the Earth blocks them. Scanning the pyramids (fun fact: you can DIY a muon detector for If you wanted to image underground with muons, you're basically using them as backlight- muons come from behind the detector, penetrate the ground, and occasionally reflect backwards into the detector. Since the return point and angle are random you wouldn't be able to do it without a very expensive muon source or detector.

Is there hobbyist ground penetrating radar?

Yes. I've got a friend who digs privies for fun (that's a loaded intro, search for The Privy Diggers or The Boghouse if you're curious) and he bought a GPR cart last year for a pretty reasonable price - I think the price was in the hundreds, rather than the thousands. Some guy assembles the electronic components into a Pelican case, essentially, and it hooks up to free iPad software.

This got my curiosity peaked. I was able to dig up an open source GPR rig that even utilizes building a rover to do scanning.

#9Looks like we're entering a Golden Age of non invasive archeology!

#10I always thought something like the Ground Penetrating Radar GPR would be very useful to determine where to the ruins are and avoid them while building a subway.
One of the (many) reasons why Rome has only 3 subway lines is that it's very common to find ancient rome building while digging.
