Looking roughly south: Sandy Hook is barely visible at upper-right, Rockaway inlet at the upper-left, Brooklyn at lower-left, Staten Island at lower-right. The shipping channel is also plainly obvious.
This bay is muddy and turbid, although some folks dive the several small wrecks around the inside of Sandy Hook. Bottle hunting around the old piers and pilings in Keyport harbor is also a possibility, but most of the structures along the bay shore are too small and shallow to be of interest. I have scouted the shoreline from Atlantic Highlands to Laurence Harbor, and nothing looks too promising. See also entries on Navesink River and Horseshoe Cove.
