Idaho trip, 7/21 - 7/28 2010
Wes taking a photo of a flower growing.  Amazing to see a flower growing in such conditions!The two types of geysers are fountain geysers (which shoot water out in various directions through a pool) and cone geysers (which shoot water out in a fairly narrow jet, usually from a cone-like formation). All these are at West Thumb
The microorganisms which live in and around the hot springs often make the pools very colorful.Yellowstone contains the majority of the worlds geysers. Within Yellowstone's thermal features can be seen the product of millions of years of geology at work.

Geyser pool with steam coming off it.Much of Yellowstone sits inside an ancient volcanic caldera (the exploded crater of a volcano). The last major caldera forming eruption occurred 600,000 years ago. Hot Springs are similar to geysers, but their underground channels are large enough to allow rapid circulation of water.Rising hot water releases heat energy by evaporation or hot water runoff, while convection currents return the cooler water to the underground system, thus maintaining equilibrium.

There are a number of fumaroles, steam vents, located at the higher elevations in the Fountain area.You can see steam coming off this geyser.  the water is boiling temp.For hundreds of thousands of years following              that, subsequent lava flows slowly filled in most of the caldera. Even now, in some places, nearly molten rock resides as little as 2-5 miles below the surface.Heat from the volcanic activity makes its presence known by heating ground water and creating the therma features we now see.
