Near shore, there is a clay shelf with a drop of about 5 feet, in about 25-35 feet of water. There isn't a whole lot of life on the shelf, since it is clay, but there are occasional fish or other critters hiding in the undercut of the shelf. All in all, this is a very interesting dive site. One of the major drawbacks to diving the Narrows is that the walk from the parking lot to the beach is very long, and very steep. Fortunately, is a paved road.
Access is across the railroad tracks, and down the rocks that armor the train tracks.
Also, care should be taken while crossing or walking along the tracks, because the trains often travel fast, and don't often sound their horns. The can take you by surprise if you're not alert.
