The Verrazano Narrows at the mouth of the Hudson River.
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.
The Alexander Hamilton was the last of the steam-powered side-wheel riverboats of the Hudson River Day Line. Built in 1924, she ceased operations in 1971. A well-meaning group pulled the Hamilton from the mud in 1977 and moved her to a temporary berth along the east side of the Navy pier, planning to restore her as a museum. Unfortunately, at the new more-exposed location, the old vessel was sunk and reduced to scrap by a sudden storm in November of that year. The last records indicate that the wreck is still there, and you can even make out the outline on Google Earth.
A very small wreck, consisting of a primitive single-cylinder steam engine and a large, completely broken-down boiler. Odd pieces of pipe and machinery lie around, but no remains of a hull, although there appears to be some iron plating under the engine. Guessing from the technology, the construction would date to around 1860 +/- 10 years, and the sinking would have been sometime after that.
