Mudboy,
What you are seeing are the remains of a small farm that was still functional into the 1950's. They sold to the State and it was absorbed into Wharton. The name was Kosowski os something close to that. Guy should have the actual name.
The general area is known as Chewtown, a.k.a. Chuton, which is centered at the intersection of Chew Road and Sandy Causeway. There are plowed in remanants of another foundation on the NW corner of the intersecction. Yucca plants give the location away. The foundations you are referring to are further north into the woods where Fleming intersects.
The cemetery in the woodcutter's property on Chew Road is a Chew family cemetery.
A very old friend of mine from church who maintains the cemetery, told me that his mother was from Chewtown and his father was from Dutchtown, around the corner on 206. He always asks me how things are going back in Chewtown whenever I see him.
If you look at the 1930 aerials on this site in the area of your foundations, you can clearly see the farm. I like that area and have killed some nice deer in there over the years.
I like the foundsation with the supports in the floor. I was told by some local oldsters that they were for whiskey barrels.
Another local legend is that the family that lived on the farm that you are asking about had a daughter that they treated like a rented mule.
One night she had had enough and laid down on the JCRR tracks right there and was killed.
I have never sought any corroboration on that tale.
