Last month when I read about the Hopkinton site on the Rockpiles blog, I made some LIDAR images of the area. I have never been there, and wanted to see what features I could find for a later visit. Here are the best LIDAR images. If anyone would like LIDAR images for illustrating the features of this site, I would be glad to send them in JPEG or TIF format. Close-ups and different views can be made from the source data.
The area to the lower left in purple has plenty of walls and rounded structures indicating boulders and large rock piles. The conical objects are tree artifacts. The details are lined out below.
Dirt roads are dotted lines, and the walls are drawn in at lower left. The Z-axis was slightly exaggerated to bring out details. The area directly south also has many stone walls. The larger square objects are houses.
Here it is marked.
The view directly west of the first area shown has a road lined with houses. This area is also strewn with boulders.
The LIDAR data files used to generate these images are too large to be tiled together for a continuous image.
