I finally saw the difference between old school digging and modern ground-penetrating radar

For years, I thought careful trowel work was the only real way to find things, based on my volunteer time at a local site. Then, last spring, a team near Tucson used GPR before they even broke ground and mapped a whole pueblo layout in two days. It showed exactly where to dig, saving months of guesswork. Has anyone else worked on a site where tech like that completely changed the plan?

Watched a team use drones with thermal cameras over a field in Cornwall last summer. They picked up on buried stone walls from a medieval farm no one knew was there, all before lunch. Makes you wonder what we walked right over for decades, doesn't it?

Honestly, that's wild. Tbh we probably spent centuries farming right on top of a whole history lesson. Ngl, makes you picture some guy in the 1800s complaining about hitting rocks with his plow, never knowing he was wrecking his own ancestors' kitchen wall. All that time we just needed a fancy drone and a sunny morning.

Right, the guy with the plow hitting rocks. I bet he just cursed and threw the stone, never thinking he just chucked his great-great-grandma's favorite cooking pot across the field. All that back-breaking work for nothing, and now some grad student with a tablet finds the whole village during their coffee break. It's kind of hilarious and sad at the same time, lmao. We spent so long just digging random holes like idiots.
