Dry lake in the Searles Valley of the Mojave Desert. The evaporite basin is approximately 19 km (12 mi) long and 13 km (8.1 mi) at its widest point. The mining community of Trona is on its western shore.

Borax is mined since 1873. Nowadays also sodium sulphate, sodium carbonate and sodium chloride (halite) are produced.
