Soap Lake, seen above, is the last lake in a series that's nestled between basalt cliffs that form the Lower Grand Coulee of Washington State. Carved over thousands of years by the successive floods of Glacial Lake Missoula, the cliffs to the north of the lake are dramatic evidence of the power of the great floods. Soap Lake is meromictic with two permanent and stable layers. The bottom is hypersaline, sulfuric and cold, while the top is an anaerobic brine similar to seawater. The lake is approximately 2 square miles (5.2 sq km) in area and 70 feet (21 m) deep at its deepest point. Photo taken October 20, 2020.
