Colorful bands of algae and diatoms in the Great Salt Lake, Utah.

The hypersaline lake covers 1,700 square miles but has a maximum depth of about 35 feet. It’s typically 3 to 5 times saltier than the ocean and fish free. The phytoplankton blooms in January followed by several species of diatoms.

The subject of Puzzle 44, this is a photo from the air. For the flickrcaching crew, here is a movie of an “extreme telephoto” zoom into the nearby stadium.
