Dramatic change in the area of the Great Salt Lake over the past 25 years. Left: August 1985. Right: September 2010. The lake was filled to near capacity in 1985 because feeder streams were charged with snowmelt and heavy rainfall. In contrast, the 2010 image shows the lake shriveled by drought. // Credit : USGS Landsat Missions Gallery
