Marker SE of Treasure Island

I came across a black and white marker the other day that was very confusing... It's located about 500 feet SE of Treasure Island. I guess in the past I've always been more in the channel between Treasure Island and Alton and never noticed it.

Since it's SE of Treasure Island and it's a black and white marker, that would say you should pass between it and Treasure Island if I'm travelling East. Usually if there is an offshore hazard, there will be a red and white marker in the area too marking the opposite extent of the hazard. In this case there isn't one.

Looking at the Bizer map, it shows a depth of 5 feet North of the marker and plenty of water South and West. Of course I couldn't see that at the time since that area is in the break area on the laminated map I have on the boat.

What am I missing here? Another boat was kind of looking at that marker too and he decided to to go South of it. I went North of it (between the marker and Treasure Island). Neither of us hit anything. If it's really marking shallow water between it and island, I'd think it would be red/white.
