The Bonneville Salt Flats is a salt deposit
left by the receding of ancient Lake Bonne-
ville. 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 aggre-
gate, porous, hard and rigid so that it sup-
ports loaded trucks.
In 1912 this area was tested as a race track
and has since proved to be the greatest auto-
mobile speedway in the world. In 1931 Ab
Jenkins of Salt Lake City broke all former
world speed records.
Here on September 15, 1938, John Cobb
established a record of 350.07 miles per hour.
The next day Captain G. E. T. Eyston set a
world's record of 357.50 miles per hour.
Aug. 26, 1939, John Cobb again became the
world's automobile speed king by driving his
car 369.74 miles per hour.
