I wanted to have a better look at the area with the pile of bricks and the area on the East side of the reefs so I swam out again on Dec. 29, 2014. There was a strong wind blowing and the choppy waves made it difficult to swim on the surface so I followed my compass out underwater. At the tip of the reefs, the area with the bricks was pretty extensive. The East side of the reefs dropped to a flat sand-dune bottom about 15-20' deep. I didn't see any wreckage here except for some kind of aluminum beam lying on the side of the rock slope. Up near the exposed rocky islets, the 6-foot breakers were stirring up the shallow bottom and the surge made it difficult to swim. I saw some heavy copper/brass/bronze wheel-type things half-buried in the gravel and nearby there was what I think is a hawse pipe. It was less than a foot in diameter and was made out of a copper/bronze/brass material. It might have been from the Discovery Isle wreck, but it was pretty far away from the engine/shaft.

The engine and shaft (from the Discovery Isle?):
chains running over the nearby reef
sand dunes near the engine
-Bits of wreckage near the engine. I didn't take anything from the wreck since that would be  illegal. Even if it wasn't, I find it more interesting to see the items in context on the bottom of the ocean compared to on a shelf at home. I picked up some of the pieces to get a better photo of them, but I put them back in the same spot.

Farther out along the base of the reefs there is an area with lots of bits of fiberglass-covered plywood, blue plexiglass and aluminum tubing. The collection of golf balls here makes me think that this spot naturally collects lighter objects due to currents and wave-action.
