Pyramid Lake

With the eponymous pyramid. Nevada, USA. Telephoto view from the top of the Incandescent Rocks. The location shows the pyramid in the lake, not the photo point! Pyramid Lake has no outlet; its level is set by the balance between evaporation and inflow from the Truckee River. The Truckee, in turn, flows out of Lake Tahoe in the Sierra Nevada to the west and ends here.
