Have you ever passed over a formation on SI that reminded you of something? Sort of like seeing familiar things in clouds. Well, that happened to me today. I was passing over a featureless area while trolling and a face jumped out at me. I turned the boat around and went back over it and, sure enough, a face.
I have added the SI screen capture as well as a zoomed and cropped image as well. I tried coming at it from the opposite direction and nothing but a hump. The eyes, nose, and mouth were formed by the sonar shadow which didn't appear from the opposite direction.
Share your images if you have something as well.
