I used a drone for a site survey and it showed me something the ground team missed

Last spring, I was helping map a potential dig site near Taos, New Mexico. Everyone on the team was focused on the main mound, convinced it was the only feature. I decided to fly my DJI Mini 3 Pro over the whole area, just to get a wider look. The photos showed a clear, straight line of darker soil about 50 meters west of the main site, something you couldn't see from the ground at all. I pointed it out, but the lead archaeologist dismissed it as an old irrigation ditch. We got permission for a small test pit anyway, and it turned out to be a collapsed wall from a much earlier period. It made me learn that sometimes new tools show us things we aren't ready to see because they challenge the expected story. Has anyone else had a simple tech tool completely shift their initial site assessment?

Honestly... I get why the lead person was doubtful. Sometimes a straight line is just a ditch. Relying too much on drone shots can send you chasing shadows while the real find is right under your feet. New tech is cool but it can make people ignore simple, on the ground work that actually tells the story. We almost missed a key hearth once because everyone was staring at the fancy 3D map instead of the dirt. That wall find was lucky, but it could have just as easily been a waste of time.

Ugh, that hearth story hits home... @tarag28, what finally got your team to look down at the dirt instead of the screen? Was it one person just getting fed up and starting to dig, or did the data itself show a weird spot that needed a real check? I've seen crews get so stuck on the pretty pictures they forget the map isn't the actual ground... it's just a guess until you put a trowel in it.

Flagged three ambiguous spots in the GPR data and dug test pits in each.
