Big Cone, West Thumb Geyser Basin, Yellowstone. Behind the cone is Yellowstone Lake, with rain falling on the Absaroka mountains. Shot taken with a 50mm lens on my Canon 5D, ISO 100, f/9.0, and a longish exposure of  1/50 seconds. &quot;Jutting out into Lake Yellowstone, Big Cone, a companion to Fishing Cone, is a large sinter cone, and is sometimes seen completely submerged by the lake. Eruptions from this geyser are rare, and only reach heights of one foot or less.&quot; - West Thumb Interactive Tour
