A lighthouse is a ruler if you leave it alone long enough.
Sandy Hook Light was lit in 1764, five hundred feet from the end of the beach. The tip is a mile and a half past it now.
The lighthouse never moved. The beach did, about three feet a year, every year, since before there was a country to put it in.
The ground here keeps telling that story at different speeds. The bluff under the Highlands is a sea floor from the last million years of the age of dinosaurs. Under New York Harbor there is a river nobody sees, cut by the Hudson when the coast ran eighty miles east of here.
Twenty thousand years ago the sea stood four hundred feet lower, which makes the shoreline you grew up on younger than the pyramids.
