...but what? When I know for sure, you'll be the first to know. But seriously, aside from the fact that one of its famous landmarks looked more like a UFO impression than a volcanic island, when I captured this image there was a real sense that I had been the one who landed on some distant piece of land - like the moon.
The photo below is the actual sign presenting Mono Lake, in Lee Vining, California. As you can see, a piece of its volcanic rock is dangling from the sign to give one an opportunity for closely inspecting its texture.
That's all for now.
