I'm not affiliated with the site I submitted, but some just really love stone walls, especially those of us here in New England. I'm part of a "New English Stone Walls" Facebook group that has ~65,000 members.

To me (I'm in CT) there's something really cool to be in a forest surrounded by trees but see a perfectly made stone wall just there in the "middle of nowhere." I think about how much time and effort it took back in the early ~1800s to clear all that land, move all those rocks across fields without modern machinery, and put so much effort into constructing these walls. Some are over 6 feet wide and many are in incredible shape for being put together ~200 years ago.

There's also the "Stone Wall Initiative" spearheaded by Robert Thorson of the University of Connecticut that also has tons of info:

(He also has a really good "Stone by Stone" book available on Amazon.)

My first thought is for historical research. It would be quite a bit of help if you have some old town or settlement map that you can compare to/overlay with a LiDAR stone wall map.

I am not sure, but it may also serve historical preservation purposes if that is an issue, e.g., if administrators are deciding on land partitioning and/or development plans.

It could be used to enhance topo maps for hiking. If you’re lost and come across a stone wall, you now know where it possibly leads.
