Today, over 500 teams from around the world have gathered on Utah's sun-baked Bonneville Salt Flats, bringing their high tech (and vintage) motor vehicles to the 63rd annual Bonneville SpeedWeek. The Southern California Timing Association hosts the annual event on the hard salt shell that covers the desert floor, setting up straight tracks that can reach as far as nine miles. Records are already being set this year, with speeds reaching over 350 miles per hour (560 kph). Reuters photographer Jim Urquhart traveled out to the scene near the Utah/Nevada border to capture some of the sights of Bonneville SpeedWeek 2011.
