It’s hard to give the exact dimensions of Columbia Island, a small piece of bedrock off the coast of New Rochelle, N.Y., because the tide changes its dimensions so dramatically.

In a 1966 article announcing that the “Radio-TV Couple” Peter Lind Hayes and Mary Healy had donated the island to the College of New Rochelle, the New York Times claimed that it “varies in size from about an acre to 175 square feet,” though that’s not quite right, given that even at the time the island was the site of a roughly 5,000-square-foot bunker that had been the base of a 400-foot-tall broadcast tower.
