A construction crew in Boston stumbled upon an "incredibly rare" find beneath the city's street: a 19th-century shipwreck. "Nothing like this has been found in Boston, in filled-in ground, before," City of Boston archeologist Joe Bagley said. "This is incredibly rare and incredibly amazing." The ship is a wooden sloop that's at least 50 feet long, according to CBS News, dating to the mid-to-late 1800s.
