Cratère de Lonar

"Approximately 50,000 years ago, a meteorite traveling at about 11 miles per second slammed into India’s Deccan Plateau. The collision formed Lonar Lake, the one of the largest, most unique basalt impact craters in the world. The oval-shaped crater, which has a circumference of about five miles at the top, is both saline and alkaline. Perennial streams and springs feed into the lake. It’s home to a horde of algae and plankton species that thrive in its unusual ecosystem and give the water its vibrant color."
