Two two locations I linked to are the only two that I've found that have this grid pattern.
You are no doubt correct about this location. Here are some other examples: https://boydsmaps.com/#18.00/39.632185/-74.688277/midatlidar/0.00/0.00I think they're all over the place, if you look for them! This one is interesting, looking all the way back through the aerials, it just appears to be a wooded area. But on the 1930's aerials, it looks sort of like an old field.

I'm thinking these are old tree farms/nurseries.
Guy, do you think the features I am looking at near Hawkin Bridge are remnants of the farm?I suspect the house for the farm at Hawkins Bridge is the large cellar hole right along the road at the top of the hill.
The features at Washington most likely is the Sooy properties N.P. Sooy, P.S. Sooy Job W. Sooy had three lots at 10.5177 acres, 15.6947 acres and 4.4115 acres.The property stones were still there when Wharton was purchased. I went there years ago after a very crispy fire where all you could see was dirt and I did not find the stones.

That's some kind of artifact, probably the result of the workflow I used when creating that map. That was one of my first 3d maps using the MapBox API and I didn't quite understand a couple of the finer points (you need to figure it all out for yourself, they don't support making you own maps with your own data).
