Minor tributaries of Threemile River - Westville, Taunton

I thought it would be fun to go a bit further afield, to Taunton. My center of gravity is southern Rt 495 and it was only about 20 minutes from the highway. Instead of walking north from where I parked I saw an inviting "corridor" down into a wetland to south [see here], and I followed it.I followed it until I got to a funny little stretch of stone wall and started seeing rock piles after that, as I continued down the wetland [lowest blue outline].

These piles were not much to look at:

Perhaps the nicest one:

These piles are not of a style I recognize. I did not see any even spacing. I did see a few "gap" piles, like these:

Also this seemed to be a place with many short stretches of wall:

 And fainter:

I could have continued down the wetland because there seemed to be a continuation of the things I was seeing. Again, these are not a familiar style: they are not marker piles, they are not mounds. A few piles were small and circular, like fire rings without charring. There were piles right within the wetland and the "gap" piles suggest a place of movement and pathways. 

Instead of continuing downhill, I cut east and found some more traces on a high outcrop looking east. Here the ridge was modified:

Eventually, I turned north, crossed the dirt portion of Rocky Woods Street, and went down along the north side of the land, south of Fall Brook, heading back west. Eventually I came upon some really old mounds [upper blue outline]. I doubt very much whether anyone would see these, or agree that they are man made mounds. But they are.

 [Here is something very unusual: quartz used to wedge a split rock. My thought is that you would rarely want to amplify the spirit of a split rock.]

 Here is another of those invisible mounds.

and others:

The general observation is that these seem to have two or more large rocks at their periphery and, otherwise, are completely broken down - nth stage decrepit. All of which makes this place, at the very highest headwaters of Fall Brook, seem quite old.
