Evaporation Ponds Near Great Salt Lake
August 06, 2012
The photo above shows an airborne view of evaporation pond clusters adjacent to Great Salt Lake in Utah. Water from the Great Salt Lake is pumped into the desert flats that border the lake and when this water evaporates, salt, potassium, calcium and other minerals, are left behind. The colors of the ponds result from both the variations in salinity and from the algae content. Note that smoke from wildfires in Colorado made the sky a bit hazy. Photo taken through my Cessna 172's open window, some 1,000 m above the surface, on July 9, 2012.
