This Nov. 28, 2012 photo provided by The United States Coast Guard shows a World War II minesweeper on the Mississippi River near St. Louis. The lack of rain has left many rivers at low levels unseen for decades, offering a glimpse at things not normally seen. The minesweeper, once moored along the Mississippi River as a museum at St. Louis before it was torn away by floodwaters two decades ago, has become visible _ rusted but intact.
