Yellowstone National park is a geo thermal wonderland, world's first national park and is also one of the supervalcanoes of the world !! Prismatic, colorful hot water pools, geysers, lush meadows, waterfalls, rivers and wildlife will take your breath away!! About two third of world's geothermal features are in Yellowstone NP. When eye witness described these features in the area in 19th century, no one was willing to believe. In 1871 the Hayden expedition set out to survey the sources of the Missouri and Yellowstone Rivers. Thomas Moran joined as artist of the team and painted many of Yellowstone's geologic features and landscapes. That helped convince the Congress to declare the area what we now know today as the world's first national Park.
Technical info: All the pictures are single shot images. No fanciful HDR and no merging of multiples exposures involved. I do not use Photoshop. Images shot as raw files and processed in Lightroom
