I was curious so I did some digging. Turns out there a few I was able to find that can be reasonably attributed to ancient humans. I found this site [1] that mentioned a name which turns out has a Wikipedia page [2] that talks about a stone chamber that was likely built in 2000-770 BC as an astronomical calendar.

Most of the literature attributes the walls to early settlers and colonists. The vast amount of walls especially in places that were never settled makes this hypothesis wrong and outright misleading. Some walls were created by colonists but you would need millions and millions to make all the walls in this region.

The early colonists were substitance farmers and there are no journals or diaries or documents which talk about building walls.

They do have diaries of farming and painting and all other topics but not building walls up mountains and sprawling over legde and landscapes.

What if there were people in the Americas before the colonists!

What if the colonists occupied the land those people had farmed!

I'm also interested in learning more if you have references/links you'd like to recommend.

Additionally the Native Americans never laid claim to making any of the rock walls in this region.

Search up liDAR and New England. The region is still being scanned but each time they scan more and more walls are illuminated.
