A World's Record Breaking Racer on the World's Fastest Speedway.
| Bonneville Salt Flats near Great Salt Lake, Utah. The Bonneville Salt Flats is a salt deposit left by the receding of ancient Lake Bonneville. This deposit covers about 159 square miles extending some nine miles along U.S. Highways 40 and 50 and the Western Pacific Railroad. The salt is white crystalline aggregate, porous, hard and rigid so that it supports loaded trucks. In 1912 this area was treated as a race track and has since proved to be the greatest automobile speedway in the world. In 1931 Ab Jenkins of Salt Lake City broke all former speed records. Here on September 15, 1938, John Cobb established a record of 357.50 miles per hour. Aug, 26, 1939, John Cobb again became the world's automobile speed king by driving this car 369.74 miles per hour.|
