The full version of this orthorectified image shows Mono Lake, a large, shallow saline lake in Mono County, California. Because it lacks an outlet, dissolved salts make the lake very alkaline and salty.

Mono Lake is in a geologically active area at the north end of the Mono-Inyo Craters volcanic chain and is close to Long Valley Caldera. Volcanic activity continues in the Mono Lake vicinity.

Two main islands can be seen in the lake: the larger Paoha Island and the smaller Negit Island. Both islands are of volcanic origin. They are separated by a narrow channel. During low water levels, Negit Island and eventually Paoha Island become connected to the mainland in one giant peninsula. Here, the water levels are high enough so as to separate the islands.
