This photo was captured by the Old Faithful Webcam on March 9, 2006 in Yellowstone National Park, Wyoming. As shown above, late winter tourists line up to witness the eruption of the Old Faithful geyser. The cold and foggy weather is not very visitor friendly but does little to deter the curious guests. This iconic geyser is one of many in the park that occur when ground water becomes superheated by magma very close to the surface. Geyser eruptions result when the superheated water is forced through joints and passage ways to the surface. Eruptions only temporarily reduce subsurface pressure and decrease the water supply -- they're soon re-supplied and re-heated for the next outburst.
