Earth Science: The Spotted Lakes

The lake appears to be a normal one during fall, winter, and a small portion of spring; but during the summer, most of the lake becomes evaporated. Dozens upon dozens of crater-like mineral deposits rest at the bottom of the lake and become visible during the warm weather. The mineral deposits span about 25 feet on average and contain many different concentrations of magnesium sulfate, and calcium/sodium phosphates, which gives them a distinct yellow, orange, green, or blue color.
