Fish farms. In actuality these things aren't very big compared to the wake left by a runabout. But... looking out of place in the way they sit.I believe it to be an image error. Look at the scale. It would be huge. And very expensive. I have seen these errors before. Another image inserted within the image.....on google maps. It might be because they are constantly updating map images/information. Bound to goof up once in a while. Try another map service and see if it is there.
Fish farms if in the ocean. I am not sure even as they look out of place due to the texture or grain.View attachment 2277
Any ideas on what this could be?
