Sept. 5, 2010 - Mono Lake, California, U.S. - Kayakers paddle near tufa towers on Mono Lake near Lee Vining, California. Mono Lake is a majestic body of water covering about 70 square miles. It is an ancient lake, over 1 million years old -- one of the oldest lakes in North America. It has no outlet and no fish; instead it is home to trillions of brine shrimp and alkali flies.
