The Mammoth Hot Springs are on the north end of the Yellowstone National Park. The area housed a Military expedition that was used to "tame" the area in the early days. The hot springs are composed of a number of terraces with bubbling hot springs that drain downhill, forming the terrace features as the minerals in the water settle out into the landscape. The grey-white limestone deposits are called travertine. The material looks a lot like snow or ice from a distance. You can also see a storm which moved into the area while we were there and chased us back into the car. This image was taken with my 24mm lens and an exposure of 1/320 seconds at f/5.6, ISO 100.
The trails for visitors are on man made boardwalks to allow visitors to get close to the hot springs without damaging them. Looking down into one of the terraces below the boardwalk shows the pools of water in the terraces and shows some of the structure found in the terraces. This image was taken at 75mm focal length with an exposure of 1/250 seconds at f/5.6, ISO 100.
These fresh terrace structures show the wide variety of colors and structures. Some of the features almost look like snow and ice structures. This image was taken with my 24mm lens and an exposure of 1/400 seconds at f/5.6, ISO 100.
A closeup of the terrace from the previous image showing some of the complex structures and perhaps you can see the slow trickle of water flowing downhill. This image was taken at 75mm focal length with an exposure of 1/320 seconds at f/5.6, ISO 100.
The travertine covered landscapes have a variety of textures and colors to be seen. This image was taken at 75mm focal length with an exposure of 1/200 seconds at f/5.6, ISO 100.
This is a lower pool at the top of one of the lower terraces. The pools can be seen steaming and it produces very colorful deposits. This image was taken with my 75-300mm lens at 75mm focal length with an exposure of 1/320 seconds at f/5.6, ISO 400.
