More SEALAB Photos

A SEALAB Diver wearing a Re-Breather Scuba System tested in Morrison Spring


Note there are no bubbles!

Taken from inside the First Cave, looking out.

In the background,  the

cypress log can be seen.


That log was placed there many years before, but I never learned who placed it, or why.

The log provided a handy place to anchor the large inner-tube that we placed over the “boil”.

Mercury Seven Astronaut/SEALAB Aquanaut Scott Carpenter made many dives at Morrison Spring during the six years that SEALAB tested equipment at the Spring. 

My dad was especially proud to be presented with that autographed picture.

Inside the First Cave, near the back of the cave, looking toward the entrance.

At the top of the picture you can see air trapped in the cave ceiling, creating a mirror-like image.

The First Cave’s large air pocket is above the ledge on the right, just out of the frame.  A diver could stand on that ledge and be head and shoulders above the water level inside the air pocket.

A SEALAB Diver near the crater, wearing “Double-70’s”

A SEALAB Diver sitting on the log


His tanks are “Triple-38’s” - three tanks connected together with one air manifold, each capable of holding 38 cubic feet of air at 2400 psi.

“Double- 70’s” were more commonly used, but the 38’s were smaller in diameter, with a much lower profile, allowing Navy Divers more maneuverability under water
