Soap Lake is a meromictic soda lake in the town of Soap Lake, Washington formed by the Missoula Floods at the foot of the Grand Coulee. The lake gets its name from the naturally occurring foam that gives its water a soapy appearance, and because the lake's mineral-rich waters have a slick, soapy feel. The lake is approximately 2 square miles (5.2 km2) in area and 70 feet (21 m) deep.

Insider tip — Bathe in the evening — the soapy water leaves a unique mineralizing film that protects the skin — bring your own shampoo.
