The long lasting foam on Great Salt Lake is one of its unique features. Foam is caused by waves making bubbles but it cannot form on high surface-tension water like very salty lakes. But Great Salt Lake has abundant phytoplankton that create a surfactant or soap-like substance. This surfactant lowers the surface tension allowing large quantities of stable foam during windy days. Another part of the surreal and wonderful Great Salt Lake landscape.

The hopper salt crystal buttons on the sample were created by jewelry artist Mary Lambert.
