SI Fun: Can you Find and Name the 3 Man Made Structures?

[Doug Vahrenberg]

Here is a screen capture from my Humminbird in 455kHz and showing 304' of bottom coverage. It shows 3 Different Made Made Structures in the Image. Can you locate and name all 3 Structures made by Humans???

[Doug Vahrenberg]

Here it is...

1) Road Bed
2) Fish Hatchery
3) Grits Mill RunWay

And there is some brush.



And I just realize this was with a Humminbird 1st Generation Unit 987c since date was in 2006. THe Second generation technology changed the direction and frequency of the SI Beams and created crisper details in the images.

Here's another image of the Hatchery



Grits Mill from another Angle and 2 Years Later with the 1197c and Gen2 Technology:
