In this Monday, July 20, 2015 photo, Bill Lattin, the Southern California Timing Association president and Speed Week race director, stands in the Bonneville Salt Flats in Utah. A small city of tents, trailers and thousands of visitors appears almost every August in the Utah desert to watch cars, motorcycles and anything with wheels rocket across gleaming white sheets of salt at speeds of 400 mph. But wet weather has forced the cancellation of Speed Week for the second straight year and revived a debate about whether nearby mining is depleting the Bonneville Salt Flats of their precious resource.

The Great Dismal Swamp is a marshy area in the Coastal Plain Region of southeastern Virginia and northeastern North Carolina, between Norfolk, Virginia, and Elizabeth City, North Carolina. It is located in parts of southern Virginia cities Chesapeake and Suffolk and northern North Carolina counties Gates, Pasquotank and Camden. It is a southern swamp, one of many along the Atlantic Ocean's coast, including the Everglades and Big Cypress Swamp in Florida, the Okefenokee Swamp in Georgia, the Congaree and Four Holes swamps of South Carolina, and some of the Carolina bays in the Carolinas and Georgia. Along the eastern edge runs the Dismal Swamp Canal, completed in 1805.
