White Dome Geyser and Moon

(Click image to enlarge)

This photograph was captured early one morning as the nearly full moon set behind White Dome Geyser. This geyser erupts from a 12 foot high geyserite cone, which is one of the largest geyser cones in Yellowstone National Park. The size of the cone, the fact it is highly eroded, and the slow rate at which sinter is deposited, together indicate that White Dome Geyser has been active for a very long time. White Dome sits atop an even older hot spring formation. Eruptions are unpredictable and generally occur at intervals ranging from 15 minutes to 3 hours.
