Bonneville Salt Flats
The Bonneville Salt Flats are a densely packed salt pan in Tooele County in northwestern Utah, United States. A remnant of the Pleistocene Lake Bonneville, it is the largest of many salt flats west of the Great Salt Lake. It is public land managed by the Bureau of Land Management and is known for land speed records at the Bonneville Speedway. Access to the Flats is open to the public.

The Flats are about 12 miles (19 km) long and 5 miles (8 km) wide, with a crust almost 5 ft (1.5m) thick at the center and less than one inch (2.5 cm) towards the edges. It is estimated to hold 147 million tons of salt, approximately 90% of which is common table salt.[2]
Stardust[edit]
In 2004, the Stardust spacecraft released its sample-return capsule for a landing in the Bonneville Salt Flats after its flybys of asteroid 5535 Annefrank in 2002 and comet Wild 2 in 2004.[13]
