Bonneville Salt Flats

Area Information

Managed by the BLM as an Area of Critical Environmental Concern and Special Recreation Management Area, the Bonneville Salt Flats are a 30,000 acre expanse of hard, white salt crust on the western edge of the Great Salt Lake basin in Utah. "Bonneville" is also on the National Register of Historic Landmarks because of its contribution to land speed racing. The salt flats are about 12 miles long and 5 miles wide with total area coverage of just over 46 square miles. Near the center of the salt, the crust is almost 5 feet thick in places, with the depth tapering off to less than 1 inch as you get to the edges. Total salt crust volume has been estimated at 147 million tons or 99 million cubic yards of salt! The Bonneville Salt Flats are comprised of approximately 90% common table salt.

To aid in the management of the public lands, we ask that you follow proper land use etiquette such as Tread Lightly! and Leave No Trace.  A few examples of these principles are the proper disposal of human waste, packing out litter, and ensuring any livestock feed used or transported across public lands is certified weed-free.
