Diamond Island photos
 

Compliments of my dive buddy Leander Nichols, I post pictures we took of a dive in the Scripps area off the N.W. side of the island. More to come at a later date.

As I see the name of each photo gets lost during upload, what we have, hopefully in the order they uploaded is:
Silt-out, industrial pipe, odd aluminum pipe 1/2/3, refrigerator, and concrete whatever.

If anyone has a clue as to what the deal is with the aluminum piping let us know; This piping runs in different directions and there is in my estimation perhaps several hundred feet of it.

hazzard
 

It looks like the aluminum was secured to cinder blocks by rope and sunk intentionally. So, I would think, eventually the rope will let go, and the aluminum will float to the surface, creating a wonderful surprise for an unsuspecting boater.
Is this the case?

I could be wrong but it appears that it is cable tied around the pipe and blocks. The only reason I say that is it appears that there are kinks and bends that would not be in place if it was rope. I would be interested in knowing for sure because I think SA is right that that would make for a bad day.

OMG. Am I over-reacting to this? Someone has a drainage pipe(s) leading into the lake, weighted down with a cinder block and rope, and we can't call the EPA, Police, Obama, whomever, to investigate and stop this potential illegal activity immediately? Where is it?

Must be that super light weight aluminum that floats.:rolleye1:

oh, yeah
 

Whoops. I'll wear the dunce cap today.

Apparently I will join you:confused:

Rotfl!
 

What also floats in water? Rain, apples, very small rocks... :laugh:
Thanks for the laugh guys.

Thanks for sharing these Diamond Island underwater photos with us Diver1111, they are very interesting. Hopefully someone here will be able to unravel the mystery.

late '60's early '70's
 

I remember diving in the area off of the big boathouse on the NW corner of Diamond Island. I remember a miniature underwater railroad track with wires running down the middle. There were braces here and there sticking up out of the silt. I can't recall the aluminum ducts or the refrigerator.

The Navy and MIT were doing underwater testing in the '50's. It was classified, so that is all I know.

That testing was of laser technology and was done at night. This thread is the first reference I can recall to ductwork and a refrigerator in that area. (The refrigerator may be unrelated—it could have floated in).

1) Boats unfortunate enough to be made of aluminum will sink.

I saw that on the Internet somewhere. :rolleye2:

2) :confused: Maybe all those 100' stretches of aluminum pipe are to move silt-laden water away that would stirred up by the activity in the area. (?)

Running air bubbles through it would create the necessary current. Weights spaced at strategic locations would be needed to keep the ductwork functioning. :confused:

I've seen that aluminum tubing down there -- lots of it. Weird. I always just assumed it was more junk left over from the Navy stint. Great photos!

My Guess
 

Been thinking about what possible use the pipes could have and have a theory. If you were doing a bunch of laser experiments in the lake which required darkness and you were looking to extend your available hours for the research, couldn't you place a bunch of tubes end to end on cinder blocks to simulate dark conditions during the day?
